Does Zhang Shou’s research have anything to do with the chip? Media refusal

Some media pointed out in the rumors that Zhang Shouyi's research is not directly related to the chip.

It can be said that there is no direct relationship, but it does matter.

Zhang Shouyi's two main contributions, one is to discover the quantum spin Hall effect, and the other is to propose the theory of topological insulators.

The two are related to the information technology industry.

Zhang Shouyi once played an analogy: the movement of electronics in the chip, as if a sports car was driving in the market. They ran wildly, rambling, and the route was crooked; they continually collided, consuming energy and generating heat.

The notebook works for a long time, you can feel it is hot, this is the truth.

However, under extremely low temperature and strong magnetic fields, electrons can maintain an orderly state of motion. So, can you let the electronics run in the same way on a one-way lane under normal conditions, like the cars on the highway?

Zhang Shouyi proposed the theoretical prediction of the quantum spin Hall effect. In 2007, the laboratory of the University of Würzburg in Germany confirmed the quantum spin Hall effect and successfully experimented with mercury-deuterated semiconductor materials.

When the electrons are no longer ramped, the energy loss can be greatly reduced. This opens up a possibility to create new, low-power spintronic computing devices.

Ten years ago, Zhang Shouyi said in an interview with the Science and Technology Daily that he hopes to achieve this effect on the usual semiconductor silicon materials. This effect may be directly applied to the chip industry in the next 5-10 years. The heat dissipation problem is solved and the energy consumption of the transistor is reduced, and the life of Moore's Law can be extended.

but,From today's point of view, Moore's Law does not go to the end so quickly, and his discovery is not applied to the industry so quickly.

Let's take a look at the topological insulator.

Junior high school physics tells us that materials are divided into conductors and insulators according to their different conductive properties. Topological insulators can be intrinsically insulated and conductive on the surface because of the "extraordinary" movement of electrons. Zhang Shouyi believes that this will become a new material to replace semiconductors.

"After our technology is realized, your mobile phone needs to be charged once a week or a month." Zhang said.

In November of this year, Professor Wang Bing and Associate Professor Zhao Aidi of the Hefei Microscale Material Science National Research Center of the University of Science and Technology of China cooperated with Tsinghua University Assistant Professor Xu Yong, Professor Duan Wenhui and Zhang Shouyi to successfully prepare a single layer of tin with a flat honeycomb structure. The olefins, combined with first-principles calculations, confirm the existence of topological energy band inversion and topological boundary states.

Related reports indicate that tinene is an ideal two-dimensional topological insulator with large energy gap, and it is expected to realize the room temperature quantum spin Hall effect, which is of great significance in the application of topological electronic devices.

However, Zhang Shouyi himself said thatTinene is currently mainly in the laboratory stage, and there is still a distance from the application of mass production. He also said in 2017 that he hopes that the topological insulators will be industrialized in the next 5 to 10 years.

Therefore, Professor Zhang Shoujun's research is not related to the chip.He is researching future chip materials rather than specific chip technologies.In fact, these basic researches of Zhang Shouyi, if they can move from theory to application and from laboratory to industrialization, may indeed lead the next revolution in information technology.

But, objectively speaking, it really takes time. Experts in the chip field told the Science and Technology Daily reporter that the time required is really not short.

As for the ASML fire, the attention of netizens is somewhat offset.

On the evening of December 3, Prodrive, a component supplier of Dutch lithography giant ASML, had a big fire. ASML expected the fire to affect the shipment plan in early 2019.

Prodrive factory fire

ASML is a core lithography machine supplier to many of the world's largest computer chip manufacturers, with major customers including Intel, Samsung and TSMC. The precision of the lithography machine determines the upper limit of the chip, and ASML monopolizes the top lithography machine.

But note that this is not ASML's own fire, nor does it have the problem of destroying Chinese customer orders.It is not only Chinese companies that are affected, but I am afraid that the most sad tears are ASML itself.

Some things do happen, there is a sequence of time nodes; but before and after, it is not necessarily causal, this is the common sense of scientific thinking. Linking events that happen independently creates an “meaningful” atmosphere that attracts attention but does not necessarily respect the truth.
