Scholar’s Advanced Technological System

Chapter 456 of Xueba's Black Science and Technology System Vol. 456 The invitation to the Nobel Dinner After the frost, Jin Ling's weather was much colder. Although it was not yet winter, it was better than winter cold.

At this moment, on the campus of Jinling University, in a certain office of the Institute, there was a mist of mist on the insulation cup at the desk.

Professor Li Rongen, sitting at his desk, was drinking hot tea while browsing the meeting information on the computer.

Immediately it is the annual mrs autumn conference again, and the papers to be reported at the conference have been released for 6 consecutive years.

Whether you have time to go to the scene, this top summit in the field of materials science is something that any material person will pay attention to.

Judging from the trend of paper submission, this year's graphene research shows a blowout growth.

And the most striking one is undoubtedly the paper on graphene conducting materials.

1o1k!

The sensation caused by this number in the field of materials science can be described simply by the tsunami.

If the papers with the highest number of downloads are sorted, the papers that were posted on the official website after the deadline are rising to the top three by an incredible degree.

Although Li Rongen is not in the direction of conducting materials, he even knows less about graphene materials. His research is mainly on carbon nanotubes, but this does not prevent him from understanding what is described in the thesis and realizing its greatness ...

After reading the thesis from the beginning to the end, Professor Li Rongen put down the thesis in his hand and couldn't help but sigh.

"Great."

Graphene conductive.

This concept was a distant dream a few years ago. I did not expect that in such a short period of time, a breakthrough from the theoretical level to the application level was completed.

Not only that, from the content described in the paper, the 1o1k conduction transition temperature has not reached the limit.

In theory, as long as you continue to increase the carrier concentration of graphene, this number can be made higher ... Of course, this may seem easy to say, but it is certainly not easy to do.

Anyway, those who do research on copper oxide direction guidance materials, after seeing this paper, are afraid to doubt life.

After all, it took them half a century to raise the critical temperature of the conduction to around 125k. The advantages of graphene in terms of plasticity and engineering properties are enough to completely explode it.

It seems that these 6 professors are not satisfied with the world of lithium batteries.

Battery, lead, next?

Professor Li Rongen is only curious about one thing now. What is this guy planning to do next?

It seems that as long as he is focusing on the field, he will eventually be subverted by him.

It is not only Li Rongen who is reading this report, but also the doctoral and master students he brought with him.

After hearing the professor ’s sigh, the doctor named Zhang Fan pushed his glasses and couldn't hold his curiosity. He asked with a look of worship: "Professor, when you brought the 6 gods to do the experiment, what kind of person was he? what?"

Hearing this question, Professor Li Rongen smiled.

"What kind of person? Apart from genius, I don't know how to describe him to you."

After a pause, recalling the past, Professor Li Rongen continued.

"I won't tell you the results of the Mathematical Modeling Contest. You may have heard of it. In his sophomore year, he was able to build a model based on the experimental data I provided, and use the data collected by the Fourier infrared spectrometer to estimate the mechanical properties of the product. How much technical content is there, you think about it yourself. "

After hearing this sentence, it wasn't just Zhang Fan who asked questions. The other two graduate students in the office also showed a moving look on their faces.

It is okay to calculate materials science, and many experiments in materials science now use first-principles calculations, especially after Jin Da has gone out of the 6th boat, even if they are not in this direction, they now understand a little.

But sophomores can do that, it's really terrifying.

As for the Higher Education Club Cup ...

For these salted fish, they can win a national prize in the digital model competition, whether it is country one or country two.

Thinking that the schoolmates were so awesome, Zhang Fan couldn't help thinking about what he was doing when he was a sophomore.

However, after thinking about it for a long time, he couldn't remember anything except the name of his ex-girlfriend.

Seeing the expressions on the faces of his students, Professor Li Rongen guessed what they were thinking, but just shook his head with a smile.

"Don't be envious, either. The kid is a genius in mathematics. It didn't take long to get the Higher Education Club Cup and solved a world problem in the field of number theory. It ’s not as strong as his mathematical intuition. Simply put, a set of data is thrown at you, I can thank you for drawing a picture, but throw it at his hand, he can make you flowers Come."

Several students looked at each other.

Obviously, they did not understand what it was that Professor Li Rongen said about changing flowers.

While talking, Pei Qing, who had not spoken, finished reading the thesis and looked away from the screen.

"Professor, why do you think Professor 6 went to study the guide materials? Is there any industrial application prospect for this gadget?"

Li Rongen: "He does not necessarily study this because of the prospects of industrial applications, but if we talk about the prospects of industrial applications, its application prospects may be much larger than you think."

Pei Qing froze slightly, wondering: "Is there such a large market for guide materials?"

Professor Li Rongen shook his head with a smile: "It's more than just guiding."

Hearing this, Zhang Fan followed him and said, "Not just a guide?"

"If you don't understand, you can read the paper again. The existence of Mott insulator means that graphene can be 'open' or 'closed' under certain conditions. What does this mean? Do I need to say more?"

Pei Qing looked slightly moved: "... semiconductor?"

Professor Li Rongen nodded applaudedly ~ www.readwn.com ~ Correct solution. "

Graphene has broad application prospects in the field of electronic devices such as transistors due to its high charge carrier mobility.

However, it is well known that graphene has no bandwidth, which results in graphene electronic devices still maintaining high conductivity at any gate voltage and cannot be completely turned off, which limits its application in electronic devices.

However, the particularity of the Mott insulator has caused the material in the graphene lattice to pass quickly from the initial insulation state under the condition that a gate voltage is applied, as if there is no resistance.

There is no doubt that this is an "open and closed" state.

It is not necessary to make the entire system as low as 1o1k to realize the conductive transformation of the entire material just by using this layer of Mott insulator.

Therefore, the significance of this thesis is not just an application in the field of conducting, but also a new platform for graphene semiconductor research.

It is estimated that at the mrs conference, it is not only the energy industry that is interested, but also major electronics manufacturers will follow up on this research.

After all, graphene is a price-selling thing that is too wasteful for power transmission, but it is acceptable for electronic products.

Just then, the browser in the taskbar below the desktop suddenly flashed.

Seeing the reminder of the new email, Professor Li Rongen opened the mailbox.

When he saw the e-mail, he couldn't help but stun it slightly, and then a smile of relief appeared on his face.

"This kid didn't forget me."

Invitation to the Nobel Prize Ceremony.

He had intended to watch the event on TV, but he did not expect to have the opportunity to go to the scene ...
