Why is the World So Short of Computer Chips? What Will This Mean Going Forward?


a-silicon-wafer-in-sand-maybe (1)

Carmakers from Tokyo to Detroit are slashing production. PlayStations are getting harder to find in stores. Even aluminum producers warn of a potential downturn ahead. All have one thing in common: an abrupt and cascading global shortage of semiconductors.

Semiconductors, also known as integrated circuits or more commonly just chips, may be the tiniest yet most exacting product ever manufactured on a global scale. That level of cost and difficulty has fostered a growing worldwide dependence on two Asian powerhouses — Taiwan Semiconductor Manufacturing Co. and Samsung Electronics Co. — a reliance exacerbated by the pandemic and rising U.S.-China tensions even before the current deficit. Hundreds of billions will be spent by governments and corporations in a plethora of sectors in coming years on a “chip race” with geopolitical as well as economic implications.

1. Why are there shortages of chips?

A lot, but not all, of the disruption can be tied to the pandemic. Here are some factors:

* The stay-at-home era caused by the coronavirus pushed demand beyond levels projected by chipmakers. Lockdowns spurred growth in sales of laptops to their highest in a decade, along with home networking gear and monitors, as office work moved out of the office, and of Chromebooks as school left school. Sales also jumped for home appliances from TVs to air purifiers, all of which now come with customized chips. Even webcams like the Razer Kiyo grew hard to find after video services boomed for work and entertainment.

* Uncertainties caused by the pandemic led to sharp swings in orders. TSMC executives said on its two most recent earnings calls that customers have been accumulating more inventory than normal to hedge against uncertainties. Automakers that cut back drastically in the early days of the outbreak underestimated how quickly sales would rebound. They rushed late last year to re-up orders, only to get turned away because chipmakers are stretched to the max supplying smartphone giants like Apple Inc. 

* Stockpiling: PC makers began warning about tight supply of semiconductors early in 2020. Then by mid-year, Huawei Technologies Co. — a major smartphone and networking gear maker — began hoarding components to ensure its survival from U.S. sanctions that threatened to cut it off from its primary suppliers of chips. Other Chinese companies followed suit, and the country’s imports of chips climbed to almost $380 billion in 2020 — making up almost a fifth of the country’s overall imports for the year.

2. What’s the upshot?

Some businesses are getting whacked. Chip shortages are expected to wipe out $61 billion of sales for automakers alone and delay the production of a million vehicles in the March quarter, but the fallout now threatens to hit the much larger electronics industry. Not only cars but possibly a broad spectrum of chip-heavy products from phones to gaming consoles could see shortages or price hikes. NXP Semiconductors NV and Infineon Technologies AG both indicated that supply constraints have spilled beyond Automotives.

3. Who are the big players?

Advanced logic chips grab the headlines as the most expensive and complex pieces of silicon that give computers and smartphones their intelligence. When you hear about Apple or Qualcomm or Nvidia chips, those companies are actually just the designers of the semiconductors, which are made in factories called foundries.

* TSMC leads the industry in production capabilities and everyone now beats a path to its doorstep to get the best chips made in its Taiwan facilities. The company’s share of the global foundry market is larger than its next three competitors combined.

* Samsung, overall a bigger chipmaker because of its dominance in memory chips, is trying to muscle in on that goldmine and is improving its production technology to be widely rated as the best option behind TSMC. Companies such as Qualcomm Inc. and Nvidia Corp. have increasingly turned to Samsung.

Intel Corp., the last U.S. champion in the field, still has more revenue than any other chipmaker but its market is heavily concentrated in computer processors and production delays have made it vulnerable to rival designers that’re taking share using TSMC.

* TSMC and Samsung do face smaller competitors including Global foundries, China’s Semiconductor Manufacturing International Corp. and Taiwan’s United Microelectronics Corp. But those rivals are at least two to three generations behind TSMC’s technology.

4. What’s happening in this race?

The two Asian giants are spending heavily to cement their dominance: TSMC raised its envisioned capital expenditure for 2021 to as much as $28 billion from a record $17 billion a year prior, while Samsung is earmarking about $116 billion on a decade-long project to catch its Taiwanese arch-rival. But China is pushing hard to catch up. It’s aimed for years to reduce its reliance on US. technology, particularly in chips. The Trump administration’s efforts to curb China’s technology giants — by barring Huawei’s access to chips and and discouraging American investment in scores of players like SMIC and Xiaomi Corp. — crystallized those fears. Beijing has enshrined chipmaking among its biggest priorities in its national economic blueprints, and has pledged to spend more than $140 billion on building a world-class domestic semiconductor sector. But it has a long way to go. For instance, in the automotive sector, China has developed a large number of chip design companies in recent years but they’re still not able to make the advanced chips needed for today’s cars.

5. How about elsewhere?

Given the difficulty in developing sophisticated chipmaking capabilities, governments from Brussels to Washington are dangling incentives to anyone who will build or expand advanced facilities in their backyards. The White House is expected to sign an executive order directing a government-wide supply chain review for critical goods in the coming weeks, with the chip shortage a central concern behind the probe. The Biden administration, which is putting together a longer-term plan for chip supply, will play a key role in formulating tax incentives for a proposed $12 billion TSMC plant in Arizona and another costlier one Samsung is eyeing, possibly in Texas. And the European Union is considering building an advanced semiconductor factory in Europe with potential assistance from TSMC and Samsung. Governments including China are now considering various ways to prop up local companies.

6. Why is it so hard to compete on chips?

Chipmaking is a high-volume business that calls for incredible precision, along with making huge long-term bets in a field subject to rapid change. Famous companies such as Texas Instruments Inc.International Business Machines Corp. and Motorola have exited or given up trying to keep up with the most advanced chip manufacturing. Today most companies focus on design. With only three companies — TSMC, Samsung and Intel — still making advanced logic chips, and the American company struggling to keep up, a crucial skillset has become concentrated in the hands of just a few. Chips are made in plants that cost billions to build and equip. They have to run flat-out 24/7 to recoup their investment. But it’s not just that. Yield, or the amount of good chips per batch, determines success or failure. It takes years of knowhow and experience to get a yield of 90% out of the complex photolithographic process used to make chips. Imagine Ford being happy to throw away one car in ten. But chipmakers, who make millions of chips in a process that takes three to four months to complete, are successful if they’re hitting that mark. A foundry gobbles up enormous amounts of water and electricity and is vulnerable to even the tiniest disruptions (whether from dust particles or distant earthquakes). In 2019, TSMC shipped about 10 million advanced 12-inch wafers.

7. Who benefits from the chip wars?

Even small improvements in semiconductors can deliver substantial savings in energy and cost when multiplied across the full scale of something like Amazon Web Services. As 5G mobile networks proliferate and push up demand for data-heavy video and game streaming and more people work from home, the need for newer, more power-efficient silicon is only going to grow. One way to measure the sophistication of a chip is so-called line-widths, or the distance between circuits. The current standard in advanced chips is 5 nanometers or billionths of a meter, about a hundred-thousandth of the width of a strand of hair, although TSMC and Samsung are working on 3nm mass production by 2022. Along with 5G, the rise of artificial intelligence is another force pushing chipmakers to innovate: AI relies on massive data processing. More efficient or power-saving designs is also becoming a critical consideration given the so-called Internet of Things — a universe of smart or connected devices from the beefiest phones to the most common fridges and washing machines — is expected to swell usage of chips exponentially in coming years.

8. How does Taiwan fit into all this?

The island democracy has emerged as an industry linchpin thanks to TSMC and an entire ecosystem geared toward high-end electronics. U.S., European and Japanese automakers are lobbying their governments for help navigating the chip crunch, with Taiwan and TSMC being asked to step in. Those pleas illustrate how TSMC’s chip-making skills have handed Taiwan political and economic leverage in a world where technology is being enlisted in the great power rivalry between the U.S. and China — a standoff unlikely to ease under the Biden administration.

Samsung set to ditch lithium ion batteries for graphene, and here’s why


Samsung phones will have super fast graphene, rather than lithium, batteries within the next two years.

According to leaker Evan Blass, Samsung is developing graphene batteries for its smartphones — and we could see the first ones arrive as soon as next year.

The reason for the change is clear: exceptionally fast charging. Reportedly a full charge will now take just half an hour on a graphene battery, and despite recent leaps forward in fast-charging that would still be a significant improvement on the standard lithium ion battery.

The news is the latest update we’ve heard since Samsung reported in 2017 that they had developed a graphene ball that could charge 5x faster than standard phone batteries (reported by Cnet). So why is it taking so long for the batteries to make it onto the market? Blass surmises that’s it’s simply a question of economics: “they still need to raise capacities while lowering costs.” Once that balance is found, this tech innovation could be a true game changer.

This news comes shortly after the release of Samsung’s latest flagship phablet, the Galaxy Note 10. It boasts an impressive 3500mAh battery, while it’s big brother — the Galaxy Note 10 Plus — has a whopping capacity of 4300mAh. But they’re not just about batteries. While both run on the powerful Exynos 9825 chip, specifications diverge significantly. The Galaxy note 10 has an 6.3-inch 1080 x 2280 resolution screen, with 8GB of RAM and a triple camera set-up; meanwhile, the Galaxy Note 10 Plus has an even larger 6.8-inch screen with a sharper 1440 x 3040 resolution, 12GB of RAM, and its triple rear camera is complemented with a Time of Flight 3D sensor.

With all the recent innovations in smartphone batteries, from huge capacities to Qi wireless charging, you might have thought there was nowhere else to innovate. But graphene technology could point towards an era of even faster charging. All that’s left to be seen is how pricey is it, and whether the capacity will be enough to satisfy demanding users.

India’s first foldable phone in 2019 will be a Samsung Galaxy, A50 with Infinity-O also in pipeline … What Will this Mean to the’Flexible Electronics Markets’?


Galaxy_fold

The foldable Samsung smartphone will demand an extremely higher price for its foldable display technology. The Galaxy A50 will also bring the Infinity-O display technology to the Indian market.

  • Rumours have stated that Samsung will either use a Snapdragon 855 or an Exynos 9820 chipset.
  • Samsung said at the time that the phone will act as a conventional smartphone when folded with is a smaller display panel.
  • The Galaxy A50 will be the first smartphone in India to offer Samsung’s Infinity-O display featuring narrow bezels.

Since Samsung showed off the foldable smartphone at the Samsung Developer Conference in October 2018, the world has been eager to see Samsung’s premium lineup for 2019. The Galaxy A8s unveiled a few weeks ago showed off the Infinity-O display with narrow bezels all around. Therefore, consumers are looking forward to an exciting smartphone lineup from Samsung for this year for the Indian markets. The good news is that India will also be one of the first few markets to enjoy Samsung’s latest and greatest.

According to a report from MySmartPrice, Samsung will unveil both the Galaxy Fold and Galaxy A50 within the next few months and India will witness them soon after. The Galaxy Fold will come to Indian market a few after weeks its launch in European markets. Rumours have stated that Samsung will either use a Snapdragon 855 or an Exynos 9820 chipset for powering the foldable smartphones. Additionally, it could feature 8GB RAM and 128GB internal storage.

At the SDC 2018, Samsung mentioned that they were working with Google to optimise Android for the new foldable form factor. The optimisation with Google will make all apps, as well as the entire Android interface, adapt to the newer display. Samsung said at the time that the phone will act as a conventional smartphone when folded with is a smaller display panel. When unfolded, the device will reveal a large tablet-like display for a bigger viewing experience.

It is also known that the Galaxy Fold will feature dual batteries. Each half of the device will contain a battery, which means the Galaxy Fold could end up having a total battery capacity of up to 6000mAh. This would be necessary considering the demanding nature of the hardware as well as the software. The report also states a probable price for the Galaxy Fold. Samsung could eventually end offering the most expensive smartphones in its history by selling the Galaxy Fold for around $2,000 (approximately Rs 1,50,000). The device would be available in limited numbers as well.

Apart from the Galaxy Fold, Samsung will also bring the much-awaited Galaxy A50 to the Indian market. The A50 will be the first smartphone in India to offer Samsung’s Infinity-O display featuring narrow bezels. The panel will be Samsung’s Super AMOLED one rendering a full HD+ pixel resolution. The A50 is also rumoured to sport an in-display fingerprint sensor. Underneath, the A50 will be powered by an Exynos 9610 chipset accompanied by 4GB RAM and offered with a choice of either 64GB or 128GB storage variants. The A50 will be powered by Samsung’s OneUI based on Android 9 Pie out of the box. The A50 is also expected to kept alive by a 4000mAh battery.

The Galaxy A50 will be a midrange smartphone in India, with prices expected to start under Rs 25,000. The A50 is expected to be announced a few weeks after the Galaxy S10 is unveiled. The Infinity-O display is expected to trickle down to other budget Samsung smartphones in the future as well.

Quantum Dots and Lipid Rafts: Analytical Chemistry Solves a Nanoscale Mystery


img_0951

 

Article from Sustainable Nano

 

Remember all those great Black Friday deals on QLED televisions? You may not realize it, but they were all about nanotechnology!

The Q in QLED stands for quantum dots, which are not only being used to enhance the displays of TVs, but also are used in solar cells, medical imaging, and sensing.1-3 However, the disposal of these particles is not well regulated, leading to concern over their release into the environment. In the frenzy of holiday shopping, have you ever stopped to wonder what could happen if a quantum dot lands on the surface of a cell?

QLED

As an analytical chemist, my mind is constantly blown by the suite of analytical tools that we have in the Center for Sustainable Nanotechnology to study really hard scientific questions like this one. I recently used two of these analytical tools, the atomic force microscope(AFM) and the quartz crystal microbalance (QCM) to tackle the tricky question about quantum dots on a cell surface. In our study, we looked at how quantum dots interact with supported lipid bilayers, which (as we explained in a previous blog post) we can use as a mimic of the cell membrane. The paper was called “Quaternary Amine-Terminated Quantum Dots Induce Structural Changes to Supported Lipid Bilayers.” 4

Q dots

Let me break down why this problem is so tricky and why it required really fancy tools to be able to study it. Everything we were studying was too small to be seen by eye or even using regular microscopes – the nanoparticles were about 6 nm and the lipid bilayers were about 4-5 nm – so we needed to use tools that allowed us to really zoom in to the nanoscale to get an idea of what was happening. Furthermore, the cell membrane of an organism is naturally wet, so we needed tools to allow us to work in liquids. Finally, the interactions between nanoparticles and membranes are dynamic, meaning they can change from moment to moment, so we really wanted to use tools that allowed us to monitor the interactions of the quantum dots and bilayers over time and not just take a single snapshot.

With these requirements in mind, I set out to design a system that we could use to understand these interactions in liquid and in real time. We chose to work with supported lipid bilayers that contain something called phase-segregated domains, or “lipid rafts.” These lipid rafts are found in the cell membranes of different organisms, from plants to animals to bacteria, and are important for moving things in and out of the cell, which makes them very interesting to study. Furthermore, my collaborator, Dr. Eric Melby, previously showed that 4-nm, positively charged gold nanoparticles attached more  to supported lipid bilayers that had lipid rafts than those that didn’t (you can read more about his work here). This suggested that lipid rafts may play an important role in nanoparticle interactions with cell membranes, which was something I wanted to explore further with different types of nanoparticles, namely quantum dots.

 

lipid raft

Figure 4. We used supported lipid bilayers either with or without lipid rafts to understand the impact of quantum dots on these types of bilayers. (image adapted from Mensch et al.4 with permission from the American Chemical Society)

 

To start, I used Eric’s method of forming supported lipid bilayers either with or without lipid rafts using quartz crystal microbalance. As I’ve described previously, QCM is a very sensitive balance that uses a quartz crystal to measure changes in frequency, which we can use to figure out changes in mass. For example, if we add quantum dots to a bilayer formed on the quartz crystal and notice that the frequency starts to decrease, this tells us that the bilayer is getting heavier because the added quantum dots are sticking to it.

In my experiments, we saw that when we added quantum dots to bilayers with or without lipid rafts the frequency decreased over time (Figure 5). This told us that the quantum dots were attaching to our bilayers. Interestingly, when we rinsed the bilayer with buffer (to get rid of any loosely attached quantum dots), we first saw a decrease of mass (likely due to quantum dots leaving the bilayer) and then saw another increase in mass before the measurement leveled off. This was the first time that we had observed this type of change using QCM before. We hypothesized that this was due to the quantum dots causing some sort of restructuring of the bilayer, such as holes, multilayers, or a combination of events. But with QCM alone, we were unable to say for certain what was happening.

 

QCM.png

Figure 5. By QCM we saw that the quantum dots attached to the lipid bilayers. However, interesting frequency shifts after the rinse suggested that something more complicated was going on with these interactions. (image adapted from Mensch et al.4 with permission from the American Chemical Society)

 

Because we were uncertain what impact the quantum dots were having on the structure of the bilayer, we decided to use another analytical technique to get an actual picture of what was happening. This time we used atomic force microscopy (AFM). This technique allows us to study these interactions in liquid and over time, which if you remember were two very key factors to this work. I’ve described AFM in detail previously here, but briefly AFM works by using a very sharp tip that is attached at the end of a cantilever. We line up a laser to the end of this tip, which reflects off the tip onto a sensitive detector. As the tip scans across the sample, the laser light will move up or down on the detector depending on the height of the sample. From these changes in the laser’s position, we’re able to determine how tall features of the sample are.

 

AFM.png

Figure 6. Atomic force microscopy allows us to visualize the interaction of quantum dots and supported lipid bilayers in liquid and in real time. (image by Arielle Mensch)

 

For the first part of our AFM experiment, we formed lipid bilayers with lipid rafts. These rafts are about 1 nm taller than the other part of the bilayer. You can see this in Figure 7, where the brighter regions of the bilayer are the lipid rafts.

 

AFM lipid rafts

Figure 7. Lipid rafts within a supported lipid bilayer are ~1 nm taller than the surrounding regions of the bilayer. The 2-micrometer scale bar equals 2,000 nanometers, and the axis on the left shows you how the brightness of each region corresponds to a height in nanometers. (image adapted from Mensch et al.4 with permission from the American Chemical Society)

 

To investigate the impact of quantum dots on these bilayers, we added quantum dots to the bilayers and collected AFM images over time. This allowed us to monitor the changes to the structure of the bilayers. Figure 8 shows what we found – and it was pretty neat!

 

afm images.png

Figure 8. Sequence of AFM images showing the disappearance of lipid rafts over 15 min. The blue arrows are pointing to the lipid rafts or disappearance of lipid rafts in the images. The axis on the right shows you how the brightness of each region corresponds to a height in nanometers. (image adapted from Mensch et al.4with permission from the American Chemical Society))

 

When we added quantum dots to the lipid bilayers, the lipid rafts shrank and eventually disappeared! It only took about 15 minutes for them to completely disappear. You can see this by following the blue arrows in Figure 8. The other bright regions in the images are quantum dots binding to the bilayers and inducing structural changes (increasing the height in these regions or burrowing into the bilayer). These two changes are consistent with the mass changes we saw using QCM. We believe that the lipid rafts collapse because of an increase in energy due to the addition of the quantum dots. Basically, it is easier for the lipid rafts to mix together with the other components in the bilayer rather than stay separated.

 

Schematic

Figure 9. Schematic showing how positively charged quantum dots can cause the collapse of lipid rafts in supported lipid bilayers. (image adapted from Mensch et al.1 with permission from the American Chemical Society)

 

So, you might be wondering what all of this means. Well, to summarize, we found that positively charged quantum dots attach to supported lipid bilayers either with or without lipid rafts present. They also cause restructuring of the bilayers. In particular, when lipid rafts were present, the quantum dots actually caused the collapse of these important cell membrane components. Lipid rafts are found in the cell membranes of many different organisms, so this could have important implications in figuring out how nanoparticles affect different organisms.

But like with all good studies, there are still many more questions to explore! For this study we used supported lipid bilayers, but it would be really interesting to look at lipid rafts naturally within the cell membranes of actual organisms to see if we see the same effects. Furthermore, we can consider different types of nanoparticles with different surface coatings and see if that changes the results. So, the next time I see a QLED TV at the store, I’ll be sure to admire its beautiful colors, but I’ll also be thinking about my next research project.

Samsung to unveil quantum dot curved monitor at IFA


Samsung Curved QD 082916 cf791-qd-curved-monitor2

The South Korean tech giant is putting its curved display armed with quantum dots (QD) on its new gaming monitors to be unveiled at the upcoming IFA tradeshow.

They’re the first QD materials, or semiconductor nanocrystals, for Samsung to apply to monitors. The company has said previously that it wanted to expand QD use outside of TVs.

The CFG70 series has an 1800R curvature with a 1 m/s moving picture response time and a rapid refresh rate of up to 144Hz. It comes with the company’s own Gaming UX OSD interface, which provides an on-screen dashboard that allows users to configure settings.

Gameplay settings can be adjusted through hot keys at the front and the back of the monitor.

The larger CF791 has a curvature of 1500R, the most curved gaming monitor on the market. It has a refresh rate of 100Hz and has AMD FreeSync Technology that synchronizes the rate with AMD’s graphic cards. The monitor has a 21:9 ratio.

Samsung said the “boundless” design will allow gamers to focus on the screen, rather than the display.

“As the gaming market continues to enjoy rapid worldwide growth, gamers expect advanced display technologies that can bring out the latest video game features and optimize the gameplay experience,” said Seog-gi Kim, SVP of Samsung’s Visual Display Business, in a statement.

“By enhancing our pioneering curved gaming monitors with quantum dot technology, our CFG70 and CF791 displays further surround players and make them feel as if they are part of the game. We are excited to demonstrate this futuristic and immersive gaming environment at IFA 2016,” he added.

Samsung is reportedly working on applying curvable screens for future smartphones, and may use the technology to create a phone and tablet 2-in-1 device.

Using graphene, Samsung could nearly double battery capacities


1-Brain Transparentgraphene1-640x353Growing graphene cells directly on silicon in the lab has boosted energy density of batteries by 1.8 times compared to conventional batteries.

For all of the progress we’ve made with mobile devices, they’re still limited by relatively older technology. Namely: The batteries that power them typically get us through a day or so.

 Samsung’s research group may be on to something that nearly doubles that run-time by expanding the energy density — the amount of stored power in a given area — to 1.8 times of current batteries.

On Friday, Neowin noted that the research team published its experimental findings, explaining how it achieved this result in the labs.

Samsung’s team used silicon anodes in lieu of graphite ones; an approach many efforts in this space have taken. The challenge here though is that the silicon can expand or contract during the battery charging and discharging cycles.

To counter that, Samsung’s team created a process to grow graphene cells directly on the silicon in layers that can adjust to allow for the silicon’s expansion:

“The graphene layers anchored onto the silicon surface accommodate the volume expansion of silicon via a sliding process between adjacent graphene layers. When paired with a commercial lithium cobalt oxide cathode, the silicon carbide-free graphene coating allows the full cell to reach volumetric energy densities of 972 and 700 Wh l-1 at first and 200th cycle, respectively, 1.8 and 1.5 times higher than those of current commercial lithium-ion batteries.”

While the technology sounds promising, keep in mind that this is just a research project. Any commercial implementation won’t happen quickly, so for now, you’ll have to keep plugging in that phone, tablet or watch every night.

UPDATE: Nanoco Confirms LG Deal As Nanosys Retracts Samsung Claim


GreenerLEDLONDON (Alliance News) – Nanoco Group PLC on Friday said South Korean electronics group LG Electronics has signed a deal with The Dow Chemical Co for the supply of Nanoco’s cadmium-free quantum dots for its Ultra HD TV range, as rival Nanosys issued a retraction to information on its deal with Samsung Electronics which sent shares in Nanoco plunging lower earlier this week.

The new range of TVs from LG was launched at the Consumer Electronics Show in Las Vegas this week. The deal confirms a previous announcement from Nanoco that LG would use its quantum dot technology on its 4K TV line-up.

Quantum dots are nanocrystals made of semiconductor materials, which can be used in solar cells, LEDs and diode lasers. Nanoco’s quantum dots do not contain cadmium – a heavy metal that is restricted under European and other territories environmental legislation.

The confirmation of the deal with LG comes after shares in Nanoco dropped heavily earlier this week after Samsung Electronics unveiled new TVs at the CES event which were said to use technology from Nanoco’s rival Nanosys. Nanoco shares dropped around 18% after the Nanosys announcement on Tuesday.

On Friday, however, Nanosys issued a retraction to that statement, clarifying that its deal with Samsung only covers the patents on its quantum dot technology, not its products or technology.

Broker Liberum said this retraction is in line with its suggestion earlier in the week that Samsung will source the quantum dots for its next generation TVs in-house and reinforces its view that Samsung is likely to sign a deal with Dow for quantum dot supply in future.

“We are delighted that LG has entered a formal partnering agreement with Dow, which has the scale and expertise to meet LG’s quantum dot requirements,” said Nanoco Chief Executive Officer Michael Edelman.

Nanoco shares were up 1.3% to 118.00 pence on Friday morning.

Market Opportunities for Quantum Dots 2015-2022


Applications-of-Nanomaterials-Chart-Picture1SUMMARY

NanoMarkets believes that opportunities for commercial use of quantum dots (QDs) have changed dramatically in the past year, and this, our most recent report on QDs, identifies where the money will be made as the a result of these new trends and developments.
QDs have now exploded onto the commercial display market and are appearing in displays of all sizes, enabling LCDs with greater color gamut and lower power consumption. These QD-enhanced LCDs are already providing direct competition to OLED displays, raising the question of whether OLED displays will ever take off in the way that was once hoped.  At the same time NanoMarkets believes that ability of the QD makers to supply sufficient materials to support future growth is no longer an issue.

As a result of these trends, the granular eight-year forecasts of volume shipments and revenue generated contained in this report reflect NanoMarkets growing bullishness about QDs.  We have also considered how the QD supply chain is likely to change as the competition between QD suppliers to get the attention of major OEMs increases.
Most of the revenue generation from QDs will come from the display industry for the next few years. This is where the money is, and although 2014 saw the introduction of several QD-enhanced LCDs by a number of OEMs, QDs have still penetrated only a very small portion of the LCD market as yet.
Potential growth is huge and in the next three to eight years NanoMarkets believe that the QD industry will build upon its success in displays and expand into other commercial applications.  These newer markets are also analyzed in this report.  NanoMarkets thinks that solid-state lighting, with similar technical requirements to displays, will be the next to market. In the longer term we see potential for commercial development of QDs in solar cells and as fluorescent biomarkers, though both applications currently face substantial technical hurdles. Semiconductor diode lasers are also a potentially important application for QDs.
In this report, NanoMarkets discusses opportunities in QDs for companies throughout the supply chain – from QD suppliers to LED component makers to OEMs – and predicts how moves by these companies will affect the growth of the QD industry. We also look at the state of QD technology and what improvements will be needed to enable further growth.
