Scholar’s Starry Sea

There is another big cow who impressed Wu Bin very deeply. His name is Cao Zhengfei, a Physics Chemistry Academician, and he was selected into the "Hundred Talents Program" of the Chinese Academy of Sciences more than ten years ago. A member of the first batch of "Young Top Talent Support Program" in the country.

Currently, he is a professor in the Department of Theoretical Computing and Scientific Research of Luzhou Microscale Laboratory. His research field is computational materials science, and he is interested in the use of molecular particle dynamics to design materials with special structures and functions and to explore efficient preparation processes. He was very interested in his technology, so as soon as I heard about Wu Bin’s deeds, I came to have a good chat with him.

Finally, in the Conference Hall, there are more and more bosses, and the level of chatting with Wu Bin is getting deeper and deeper.

But after a round of chatting, a group of big cows discovered that Wu Bin is not stage fright at all, and he can express his own opinions when throwing any questions to him. will surpass us in time, the younger generations will surpass us in time......"

After the discussion, the big cows threw an olive branch to Wu Bin and invited him to their experimental team.

Wu Bin replied that he is already used to Professor Liu Yubo, and currently he is mainly studying 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 were not disappointed either. They gave Wu Bin a strong affirmation and left one after another.

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

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

"Yes." Lin Ganwang nodded, then pushed down his glasses and looked at Wu Bin earnestly and said: "As one of the countries with the richest graphite resources, now graphene has become the focus A technology, although the problem of exaggerating its role is often criticized by the industry and outside the industry, I have always 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 territory and abundant resources will finally be vividly and thoroughly displayed in China.

Lin Ganwang is nodded with satisfaction, "I believe you didn’t just choose graphene as a scientific research direction. By the way, in the previous conversation, you told Professor Cao that you think graphene is the most likely to expand. The fist is still in the transistor, is it?"

Wu Bin nodded: "This is my personal understanding. Now that silicon chips have reached the limit, more than a dozen nanometer channels are already the limit. To continue to reduce, we must work hard on nanomaterials."

"For example, carbon nanotubes before?" Lin Ganwang asked.

"Well, I have read a lot of high-level articles about carbon nanotubes. Basically, I use them and other materials to form a structure with diodes and Triode functions, but I want to use them to make integrated The circuit... is too difficult."

"But graphene is different. Although it is very thin, it can be made larger. For example, it can be processed into transistors by photolithography. With a three-dimensional structure, each transistor can easily form a small-scale integrated circuit."

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

"Yes." Wu Bin nodded, "Although graphene has an ultra-high mobility, it has no band gap. It can be regarded as a fatal shortcoming of Semiconductor application. When the preparation of this topic is completed, I should challenge how to open the band gap of graphene."

"hahaha, you are going to be the father of graphene... …Oh no. To be precise, you want to be the father of it." Lin Ganwang laughed for a while: "This road is quite difficult, even I think it is a dead end. In the chip, I think graphene It is very difficult to replace silicon. After all, graphene is far from the legendary material properties far superior to silicon in terms of performance."

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

Lin Ganwang was taken aback after listening, "You mean...Quantum computer?"

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

"Or youngster dare to think about it..." Lin Ganwang nodded, "Currently, Korea and Japan have a great deal of graphene The preparation method is actually more advanced, especially in the preparation of large-area graphene films and graphene transistors. There are many reports on the preparation of large-area graphene films and graphene transistors. However, they are very low-key for the graphene batteries that are so hot in China."

“I’ve investigated this a bit before. Samsung has invested hundreds of millions of dollars in graphene research and development in recent years, and its current patent ownership ranks first in the world. They seem to be committed to the application of graphene in all fields. Especially for the preparation of graphene and graphene flexible screens by the CVD method, their research and development capabilities are already very strong."

Lin Ganwang: "You really don't miss any news about graphene. "

Wu Bin: "After all, it is a race against the whole world. Of course I have to know where the opponent is now."

"Okay!" Lin Ganwang clapped his hands: "Already It's been a long time since a student has said such a big thing, even if it is amazing, it seems that your aspirations are far greater than I thought. "

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

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

I don't know how to answer Lin Ganwang's words, Wu Bin had to drink his mouth and smiled nodded.

"Go on, what else did you find?" "Lin Ganwang continues to ask.

"Oh, I found in the US Patent Office that Samsung currently has more than 200 graphene patents, of which 52 are manufacturing technology, 27 are transistors and touch devices. And the display, but they should still have no clue about the key technology, otherwise they would have killed Apple a long time ago. "

"Transistors are also my research direction. Short-channel effects, tunneling effects, and manufacturing processes are all limitations to the development of graphene, but they are also research hotspots. When will you be interested in this area? , You can come to my laboratory. "

"Definitely! "Wu Bin nodded hard.

Then the two talked until dinner time before saying goodbye to each other.

On the way back to the laboratory, Wu Bin was sorting out the harvest of the whole day. When the phone rang suddenly, I picked it up and saw that it was Lin Ziqi who called.

"Hello? "

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

"Russ..." Hearing these words, Wu Bin realized that he didn't seem to have eaten anything all day, so he rubbed his stomach. He replied: "ah, is preparing to go to the canteen. "

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