Xueba's Sea of ​​Stars

Chapter 202
In addition, there is another big man who impressed Wu Bin deeply. His name is Cao Zhengfei, who 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 "Youth Top-notch 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 the design of materials with special structures and functions using molecular particle dynamics and the exploration of high-efficiency preparation techniques. 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 bosses, and the level of chatting with Wu Bin was getting deeper and deeper.

But after a round of chatting, the crowd found that Wu Bin was not stage-frightened at all, and he could express his own opinion on any question that was thrown at him, which made everyone meditate in their hearts, "Young people are awesome, young people are awesome..."

After discussing for a while, the big cows offered an olive branch to Wu Bin one after another, inviting him to their experimental team.

And Wu Bin replied that he is used to being with Professor Liu Yubo, and currently he still mainly studies by reading literature, and when he finds a new research direction, he will definitely come to discuss with them.

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

In the end, Lin Ganwang was left looking at Wu Bin in the office and said: "These experimental teams have all made technical breakthroughs in two-dimensional materials, and their research fields..."

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

"That's right." Lin Ganwang nodded, then pushed down his glasses, looked at Wu Bin seriously and said: "As one of the countries with the richest graphite resources in my country, graphene has now become a key technology for future development, although its role is exaggerated. This issue is often criticized by the industry and outsiders, but I have always firmly believed that the 21st century is the century of carbon."

Wu Bin: "I agree with you, Professor."

Once graphite becomes a strategic resource, the term "vast land and abundant resources" can finally be vividly displayed in Huaguo.

Lin Ganwang nodded with satisfaction, "I believe you did not choose graphene as a scientific research direction casually. By the way, you told Professor Cao that you think the most likely place for graphene to make a big difference is in transistors." Is this one?"

Wu Bin nodded: "This is my personal understanding. With silicon chips now, the channel of more than a dozen nanometers is already the limit. If you want to continue to reduce it, you must work hard on nanomaterials."

"Like the carbon nanotubes before?" Lin Qianwang asked.

"Well, I have also read a lot of high-level articles about carbon nanotubes, basically using them and 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 by photolithography, and 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, but in actual application, 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. When the subject of preparation is finished, I should challenge how to open graphite." ene band gap."

"Hahaha, you are going 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, and in terms of chips, I think graphene is very difficult to replace silicon, after all, in terms of performance, graphene is far from the legendary material properties that far surpass silicon."

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

Lin Ganwang was taken aback 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 Huaguo can have an Graphene Valley, maybe a new road will be opened."

"It's still young people who dare to think..." Lin Qianwang nodded, "At present, South Korea and Japan are actually more advanced in the preparation of graphene, especially in the preparation of large-scale graphene films and graphene transistors. The graphene batteries that have been hyped are very low-key."

"I did a little research on this before. Samsung has invested hundreds of millions of dollars in graphene research and development in recent years. It currently has the largest number of patents in the world. They seem to be committed to the layout of graphene application patents in all fields. Especially in the preparation of graphene and graphene flexible screens 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, it's a race against the whole world. Of course I have to know where my opponent is now."

"Okay!" Lin Ganwang clapped his hands: "It's been a long time since a student has said such a big talk, even if it's bragging, it seems that your ambition is far greater than I imagined."

Wu Bin: "Is this a big talk..."

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

Not knowing how to answer Lin Ganwang's words, Wu Bin could only drink his saliva, nod and smile.

"Continue to talk about you, what else did you find?" Lin Ganwang continued to ask.

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

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

"Definitely!" Wu Bin nodded vigorously.

The two then chatted until dinner time before saying goodbye to each other.

On the way back to the laboratory, when Wu Bin was sorting out the harvest of the whole day, his cell phone rang suddenly. When he picked it up, it was Lin Ziqi who called.

"Hey?"

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

"Oh..." Hearing this sentence, Wu Bin realized that he seemed to have not eaten anything all day, so he rubbed his stomach and replied, "Well, I'm going to the cafeteria."

PS: I am very touched to see that there are so many students waiting, and I will work hard to update.
