Chapter 177 Chapter 177 How Did You Do It?

The same experimental process, the same experimental results, but in the eyes of different people, it is completely different. In the eyes of Director Lu, it is at most a novelty under extremely excited conditions; but in the eyes of Li Haifeng, a professional In the eyes of the staff, that's different.

In the past half a century of research, people have invested countless manpower and material resources in this area of ​​research, but so far only two breakthroughs have been achieved, the first time is to achieve a zt value of 1 breakthrough; the second time is that the zt value has achieved a breakthrough from 1 to 3, which is not easy;

But today, he witnessed a double-digit breakthrough under non-extreme conditions, and he felt like he was going to burst!
After leaving the front-line scientific research position, he was not that interested in academic matters. Could it be that in such a short period of time, the field of materials in academia has changed?

Unlikely, right?
The most typical feature of materials science is that the research and development cycle is long and the results are few; the achievements of materials science are all made out of money, which is difficult to match in China in this respect; the second is that there are few theoretical results, so you Go out to do other things for a few years, maybe come back and continue to do research in this field, there is still not much change, unless a large amount of investment pours into this field during this period of time, otherwise it will be useless.

And since he intends to take this path, he naturally has to pay attention to capital movements and policy changes, but he really hasn't noticed.

Given his rank and close relationship with Director Lu, he naturally did not know about this matter; and as an unlisted company, Huaneng Battery does not need to disclose his financial situation to the outside world...

So Li Haifeng made a bold guess: Could it be...that this kid was thinking about that?
Thinking of this, Li Yifeng's eyes changed, but after thinking about it, he felt something was wrong: there is no reason, how long has it been, he has already launched two major achievements, there is no reason to do such a thing, although Li Yifeng is doing research I always feel that IQ is not enough, but how many of those who can successfully graduate with a Ph.D. are not smart enough?

Thinking of this, he felt that he still needed to observe more, but there were indeed many things that needed to be asked. His foundation was still there, but the content and plug-ins had not been updated for a long time.

Of course, he didn't have the shame to go to Wang Feng to introduce him. Instead, he found another person in charge, that is, Liu Yihang. Just graduated with a Ph.D.

In fact, he guessed a bit conservatively, this young man never graduated at all!

Liu Yihang naturally does not refuse anyone who comes. In fact, he can handle inspections like a fish in water. After all, when he was in the laboratory, he was responsible for all the major tasks, especially the external one.

"Topological structure?" Li Haifeng was a little surprised: he only knew a little about this thing, not familiar with it!
"Yes, it's the topological structure!" Talking about the field he was familiar with, Liu Yihang's mental head immediately rose. Although he was patient with Director Lu in the past, he was very limited. Colleagues who can communicate (zhuang) and communicate (bi) well with themselves, naturally want to communicate.

"Topological semimetals are intermediate between metals and insulators in terms of their ability to conduct electricity or heat. Scientists around the world have been increasingly discovering that these materials have extraordinary properties, such as almost no The dissipated current and ability to convert more light into electricity than any other material hint at a wide range of potential applications, such as ultra-low power electronics and cogeneration.

In order to shorten the research and development time, we chose to stand on the shoulders of giants for further research, relying on the theoretical model of the electrochemical interface of Professor Wang, we have gone much smoother and farther than others in this respect ! "

"Wait, the theoretical model of the electrochemical interface?" Li Haifeng opened his mouth wide: "Has this been figured out yet?"

Obviously he hasn't paid attention to the latest achievements in materials science and chemistry for more than half a year, but why does he feel as if he has been left behind for so long a century?

"I can't tell you this yet, I hope you can forgive me." Liu Yihang looked at the other party apologetically, but he had no intention of explaining.

"Oh...Understood!" It should be an article that has not been published yet, Li Haifeng thought.

"We continue, there are a dazzling variety of topological semimetals, such as Dirac semimetals, Weyl semimetals, multiple fermion semimetals, etc., each of which is topologically different from other semimetals. Traditional semimetals Metals can be easily transformed into metals or insulators by changes in temperature or slight adjustments in chemical composition, whereas topological semimetals stubbornly retain their semimetallic properties despite changes in temperature or composition."

"Many physicists say that, just like graphene, electric currents can flow in a topological semimetal with almost zero energy consumption, potentially making them useful for ultra-low-power electronics," said Masaki Uchida, a physicist at Tokyo Institute of Technology. At the same time, researchers could theoretically vary the thickness of the topological semimetals to tune their properties, while atomically thin graphene has a finite thickness and is therefore less flexible for design purposes, said.

"Topological semimetals can also display unexpected properties. For example, at Boston College physicist Ken Birch and his colleagues found that tantalum arsenide can generate intrinsically 10 times more current from light as any Other materials. This effect occurs under mid-infrared light, suggesting that tantalum arsenide can be used for chemical and thermal imaging."

"For decades, scientists may have overlooked many of the salient features of topological semimetals. For example, MIT theoretical physicist Benjamin Wieder and his colleagues have just recently demonstrated cobalt monosilicide and similar This property was discovered in the material and has been studied by researchers for nearly 70 years.

"The future of topological materials discovery and application may not lie in the design of new materials, but in the rediscovery of interesting materials with overlooked properties," said Li Haifeng. "The next very popular solid-state material may be hidden if you know where to look. In a 70-year-old piece of paper."

"Fortunately, we have found one of the futures. This future is placed on our experimental platform and in the autoclave, as you can see." Liu Yihang excitedly showed their results to the other party. This part of the domestic patent has been applied for, so it doesn't matter.

And Li Haifeng also checked the equipment and data very carefully to see if there was anything missing or something that could be manipulated. If not, it is estimated that there would be more and a larger team to check every day. .
