In addition, there is a big bull that impresses Wu Bin very deeply, his name is Cao Zhengfei, he is a doctor of physical chemistry, he was selected into the "Hundred Talents Program" of the Chinese Academy of Sciences more than ten years ago, and he is a member of the first batch of "Youth Top-notch Talent Support Program" in the country.

At present, he is a professor in the Department of Theoretical Computing and Scientific Research of Luzhou Microscale Laboratory, with a research direction of computational materials science, and is very interested in the use of molecular particle dynamics to design materials with special structures and functions and explore 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 bigwigs, and the level of chatting with Wu Bin became deeper and deeper.

But after a round of chatting, a group of big bulls found that Wu Bin was not stage frightened at all, and he could express his opinions when any question was thrown to him, and everyone silently recited in their hearts, "The future is terrible, the future is terrible......

After the discussion for a while, the bulls threw olive branches to Wu Bin and invited him to their experimental team.

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

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

In the end, Lin Qianwang was left alone in the office to look at Wu Bin and said: "These experimental teams have made technical breakthroughs in two-dimensional materials, and their research leaders are ......."

"Well, I've read their literature." Wu Bin nodded and said that he knew their research direction and field.

"Yes." Lin Qianwang nodded, then pushed down his glasses, looked at Wu Bin seriously and said: "As one of the countries with the richest graphite resources in China, graphene has become a key technology for future development, although exaggerating its role is often criticized inside and outside the industry, but 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 word "vast land" can finally be vividly displayed in Huaguo.

Lin Qianwang nodded with satisfaction, "I believe you didn't choose graphene as a scientific research direction casually, by the way, when we talked to Professor Cao before, you said to Professor Cao that the place where you think graphene is most likely to show its strength is still in the transistor, right?" ”

Wu Bin nodded: "This is my personal understanding, silicon chips have been done now, more than a dozen nanometer channels are already the limit, if you want to continue to reduce, you must work hard from nanomaterials." ”

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

"Well, I've read a lot of high-level articles about carbon nanotubes, which are basically made of them and other materials to form a structure with diodes and transistors, but I want to use them to make integrated circuits...... It's just too hard. ”

"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 is a two-dimensional structure, and 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 practical 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 of semiconductor applications. ”

"Hahaha, you're going to become 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 to walk, and even I think it is a dead end, in the chip part, I think graphene is very difficult to replace silicon, after all, graphene is far from the legendary material characteristics that far exceed silicon." ”

"That'...... Perhaps graphene could become an important material for the next generation of computers? ”

Lin Qianwang was stunned after hearing this, "You mean...... Quantum computers? ”

"Yes, Silicon Valley was first named after the research and victory of silicon-based semiconductor chips, and I think if Huaguo can have a Ene Valley, maybe a new road will be opened."

"Still young people dare to think about it......," Lin Qianwang nodded, "At present, South Korea and Japan are actually more advanced in the preparation of graphene, especially in the preparation of large-area graphene films and graphene transistors. ”

"I have investigated this a little before, Samsung has invested hundreds of millions of dollars in graphene research and development in recent years, and the current number of patents ranks first in the world, and they seem to be committed to the application of graphene in all fields.

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 running now." ”

"Good!" Lin Qianwang clapped his hands: "It's been a long time since a student has said such a big thing, even if you brag about it, it seems that your ambition is far greater than I imagined." ”

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

"Of course, in the eyes of most people, isn't our country a weak country in science and technology, how dare we compete with foreign countries?"

didn't know how to answer Lin Qianwang's words, Wu Bin had to take a sip of water, nodded and smiled.

"Go on with yours, what else did you find?" Lin Qianwang continued to ask.

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

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

"Definitely!" Wu Bin nodded vigorously.

Then the two talked 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 mobile phone suddenly rang, and when he picked it up, he saw that it was Lin Ziqi calling.

"Hello?"

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

......Hearing this, Wu Bin realized that he didn't seem to have eaten anything all day, so he rubbed his stomach and replied, "Well, I'm about to go to the cafeteria." ”

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