‘Best semiconductor material ever discovered’ found US professor suspected of spying for China

Published

A team of researchers at the world-renowned Massachusetts Institute of Technology (MIT) has found that cubic boron arsenide has better properties than silicon for making microchips, calling it “the best semiconductor material ever discovered.” Notably, the team that made the discovery also included a Chinese-born scientist previously suspected of spying for China.

According to the study, cubic boron arsenide is ten times more efficient as a heat conductor than silicon. It is also the best conductor of both electrons and electron holes – this is especially important for the properties of a semiconductor. Materials such as boron arsenide could change the rules of the game in industry.

The investigation team included Gan Chen, a former head of engineering at MIT, who was under investigation for a year on suspicion of espionage, after which the US Department of Justice dropped the charges for lack of evidence.

It may well be decades before boron arsenide-based chips become commercially available—if the technology is ever found usable. Nevertheless, it is expected that the material can be used to produce better, faster and more compact chips than today.

Gan Chen was arrested in January 2021. He was accused of hiding ties to the Chinese authorities in applications for a grant from the US Department of Energy. The scientific community, including scientists from the Massachusetts Institute of Technology, criticized the arrest and wrote an open letter. Under President Joe Biden, the Justice Department dropped all charges.

Scientists emphasize that such a “witch hunt” discourages researchers, especially from China, from moving to the United States, which is why the United States cannot use its intellectual potential.

Micron invests up to 100 billion in semiconductor manufacturing in

Micron Technology intends to invest up to $100 billion over the next 20 years to build a manufacturing facility in New York State. It will produce semiconductors and become the largest in the world. It is expected that the launch of the new enterprise will create about 50,000 new jobs. As for investments, by the end of this decade they will amount to $20 billion.

Micron invests up to $100 billion in semiconductor manufacturing in New York State

Earlier in August, the company announced its intention to invest $40 billion by 2030 in memory production in the US. It also plans to invest $15 billion in a semiconductor manufacturing plant, which will be located in Idaho. Against the background of this information, the value of Micron shares increased by 3.1%.

Such large investments are not accidental – this is due to the signing of the Law on Chips and Science. According to him, US companies can receive government subsidies, $52.7 billion has been allocated for the project, which will expand the production of microcircuits and stimulate the development of the semiconductor industry in the United States.

Earlier, Intel and the Canadian company Brookfield entered into an agreement under which they will invest up to $30 billion in a plant in Arizona.

At the same time, it became known earlier that the United States wants to impose new sanctions against China, specifically related to high technologies.

Missiles no longer needed Space catapult SpinLaunch successfully sent a

SpinLaunch announced the results of the tenth successful flight test of its rocket-free space launch technology, the Orbital Launch system. During the test, the company launched a NASA payload into orbit, after which it was able to return to Earth to analyze the effect of stress loads on components.

As it turned out, elements of the satellites could well survive such an extreme launch. Indeed, with such a launch technology, the acceleration was up to 10,000 g, and the “projectile” itself accelerates to a speed of 8,000 km / h. This allows you to launch small payloads into orbit, and much cheaper than using rockets.

The tenth flight test represents a watershed moment for SpinLaunch. Today we are bringing the Sub-Orbital Booster System to our customers, strategic partners and research teams. The data and insights gained from flight testing will be invaluable to both SpinLaunch (as we continue to develop the Orbital Launch system) and to our customers who hope to that we will provide them with low-cost, high-quality and sustainable access to space”, said Jonathan Jani, founder and CEO of SpinLaunch.

SpinLaunch has been developing its launch technology since 2015, although actual launches only started last year. The company claims that their method is much more environmentally friendly and much safer than classic rockets.

At the moment, the manufacturer plans to ship about 100 units by the end of the year, and up to 1,000 more in the first quarter of 2023. At the same time, to purchase, you need to contact the supplier directly, clarify the price and specifications before placing an order.

The laptop itself is the result of a partnership between China’s DeepComputing and Xcalibyte. It is built on the Alibaba T-Head TH1520 processor with four 64-bit Xuantie C910 cores, which operate at a frequency of 2.5 GHz. It also has a neural processor with a performance of up to 4 TOPS and an Imagination graphics chip.

The laptop is equipped with a 14.1-inch screen with a resolution of 1920 x 1080 pixels, 16 GB of RAM and 256 GB of permanent memory. Other features include a backlit keyboard, SD card reader, HDMI, USB-C, USB-A and Ethernet ports, Wi-Fi 5 and Bluetooth adapters, and a 1080p webcam.

For now, such a system will be of interest only to enthusiasts and developers, but this is the first mass alternative to x86 and Arm processors that has appeared on the market.
