Chapter 202 They Are All Big Guys

There is another big figure who impressed Wu Bin deeply. His name is Cao Zhengfei. He has a Ph.D. in physical chemistry. He was selected into the "Hundred Talents Program" of the Chinese Academy of Sciences more than ten years ago, and was among the first batch of the country's "Young Top Talent Support Program". One member.

Currently, he is a professor in the Department of Theoretical Computation and Scientific Research of Luzhou Microscale Laboratory. His research direction is computational materials science. He is very interested in using molecular particle dynamics to design materials with special structures and functions and exploring technologies for efficient preparation processes. So as soon as I heard about Wu Bin's deeds, I came to have a good chat with him.

Finally, in the conference room, there were more and more big shots, and the level of chatting with Wu Bin became deeper and deeper.

But after a round of chatting, a group of experts discovered that Wu Bin had no stage fright at all, and he could express his own opinions on any question asked to him. Everyone was silently reciting in their hearts, "The juniors are to be feared, the juniors are to be feared..."

After the discussion was over, the experts all extended olive branches to Wu Bin and invited him to join their experimental team.

Wu Bin replied that he was already used to Professor Liu Yubo, and at present he mainly studied literature. When he found a new research direction, he would definitely come to discuss with them.

After listening to Wu Bin's answer, the experts present did not feel disappointed. They all gave Wu Bin a very strong affirmation and left one after another.

In the end, Lin Qianwang was left alone in the office, looking at Wu Bin and said, "These experimental teams have all made technical breakthroughs in two-dimensional materials. Their research expertise..."

"Well, I have read their literature." Wu Bin nodded to show that he knew their research direction and field.

"Yes." Lin Qianwang nodded, then pushed up his glasses, looked at Wu Bin seriously and said, "As one of the countries with the richest graphite resources, our country has now become a technology that will be focused on development in the future, although its role is exaggerated. This issue is often criticized within and outside the industry, but I have always firmly believed that the 21st century is the century of carbon."

Wu Bin: "Professor and I have the same view."

Once graphite becomes a strategic resource, the term "vast land and abundant resources" will finally be vividly demonstrated to China.

Lin Qianwang nodded happily, "I believe you did not choose the research direction of graphene casually. By the way, during the previous conversation, you told Professor Cao that you thought the place where graphene is most likely to show its potential is in transistors. Is this the piece?”

Wu Bin nodded: "This is my personal understanding. The current silicon chip has a channel of more than ten nanometers, which is the limit. If we want to continue to reduce it, we must work hard on nanomaterials."

"For example, the carbon nanotubes from before?" Lin Qianwang asked.

"Well, I have read a lot of high-level articles about carbon nanotubes. They basically use them with other materials to form structures that function as diodes and triodes. But it is too difficult to use them to make integrated circuits... "

"But graphene is different. Although it is very thin, it can be made larger. For example, it can be processed into transistors using photolithography. Moreover, it has a two-dimensional structure. Each transistor can easily form a small-scale integrated circuit. .”

Lin Qianwang nodded, "It is precisely because of this application prospect that graphene won the Nobel Prize as soon as it was discovered. However, in actual application, it is found that there are still too many problems to be solved."

"Yes." Wu Bin nodded, "Although graphene has ultra-high mobility, it has no band gap, which is a fatal shortcoming in semiconductor applications. Once the preparation project is completed, I will challenge how to open graphite. The band gap of ene.”

"Hahaha, you want to be the father of graphene... Oh no, to be precise, you want to be its stepfather." Lin Qianwang laughed for a while: "This road is quite difficult, even I think It is a dead end. In terms of chips, I think it is very difficult for graphene to replace silicon. After all, graphene is far from the legendary material properties that far exceed silicon in terms of performance."

"Then...maybe graphene can become an important material for a new generation of computers?"

Lin Qianwang was stunned after hearing this, "You mean... a quantum computer?"

"Yes, Silicon Valley was first named after the research and production of silicon-based semiconductor chips. I think if China can have an ene valley, maybe a new road will be opened."

"Young people should dare to think..." Lin Qianwang nodded, "At present, South Korea and Japan are actually more advanced in the preparation methods of graphene, especially in the preparation of large-area graphene films and graphene transistors. There are many reports, but domestic Graphene batteries are very popular, but they keep a low profile."

"I have done some research on this before. Samsung has invested hundreds of millions of dollars in graphene research and development in recent years, and its current patent holdings rank first in the world. They seem to be committed to the patent layout of graphene applications in all fields. Especially in the field of graphene and graphene flexible screens prepared by CVD method, their research and development capabilities are already very strong."

Lin Qianwang: "You really don't let go of any news about graphene."

Wu Bin: "After all, I am racing against the whole world. Of course I have to know where my opponent is now."

"Okay!" Lin Qianwang clapped his hands: "It has been a long time since any student has said such big words. Even if you are bragging, you dare not. It seems that your ambition is far greater than I imagined."

Wu Bin: "Is this considered a big lie..."

"Of course, in the eyes of most people, our country is not a technologically weak country. How can we dare to compete with foreign countries?"

Not knowing how to respond to Lin Qianwang's words, Wu Bin could only take a sip of water, nod and smile.

"Continue talking about you, what else did you find?" Lin Qianwang continued to ask.

"Oh, I found in the US Patent Office that Samsung currently has more than 200 graphene patents, 52 of which are for preparation technology, and 27 for transistors, touch devices and displays, but they still have no key technologies. I have no clue, otherwise Apple would have been ruined long ago.”

"Transistors are also my research direction. The short channel effect, tunnel effect and manufacturing process are all limitations of the development of graphene, but it is also a research hotspot. If you are interested in this area, you can come to my laboratory. "

"Definitely!" Wu Bin nodded vigorously.

Then the two of them chatted until dinner time before saying goodbye to each other.

On the way back to the laboratory, while Wu Bin was sorting out the results of the whole day, his cell phone suddenly rang. He picked it up and saw that it was Lin Ziqi calling.

"Hello?"

"Are you going to eat?" Lin Ziqi asked on the other end of the phone.

"Oh..." After hearing this, Wu Bin realized that he hadn't eaten anything all day, so he rubbed his stomach and replied, "Well, I'm getting ready to go to the cafeteria."

PS: I am very touched to see that there are so many students waiting. I will try my best to update it.
