After the frost fell, the weather in Jinling was much colder, although it was not yet winter, but it was better than the cold of winter.

At this moment, on the campus of Jinling University, in an office of the institute, there was a mist floating on the thermos cup on the desk.

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

It's going to be the annual MRS Autumn Meeting again, and the papers that will be presented at the conference have been released one after another.

Whether you have time to go to the site or not, this top summit in the field of materials science is something that any materials person will pay attention to.

Judging from the trend of paper submission, the research in the direction of graphene this year has shown a blowout growth.

The most striking of these is undoubtedly the paper on the research of graphene superconducting materials.

101K！

The sensation caused by this figure in the materials science community can be described as a tsunami.

If you sort by the papers with the highest number of downloads, this paper that was put on the official website after the deadline is rising to the top three at an incredible rate.

Although Li Rongen is not in the direction of superconducting materials, and even knows less about graphene materials, and mainly studies carbon nanotubes, this does not prevent him from understanding what is described in the paper and experiencing the awesomeness......

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

"Awesome."

Graphene superconductivity.

This concept was still an unattainable dream a few years ago, but I didn't expect that in just a few years, it has completed a breakthrough from the theoretical level to the application level.

Not only that, but from what is described in the paper, the superconducting transition temperature of 101K does not reach the limit.

Theoretically, this figure could be even higher as long as the carrier concentration of graphene continues to be increased...... Of course, this may seem easy to say, but it is certainly not easy to do.

In any case, those who do research on superconducting materials in the direction of copper oxides will doubt their lives after reading this paper.

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

It seems that Professor Lu is no longer satisfied with turning the field of lithium batteries upside down.

Batteries, superconductivity, what's next?

Professor Li Rongen is only curious about one thing now, what is this guy going to study next?

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

Also reading this report is not only Li Rongen, but also the doctoral and master's students he leads.

Hearing the professor's emotion, the doctor named Zhang Fan pushed his glasses, couldn't hold back the curiosity in his heart, and asked with a look of admiration: "Professor, what kind of person was Lu Shen when you took him to do experiments?" ”

Hearing this question, Professor Li Rongen smiled.

"What kind of people? I don't know how to describe him to you other than a genius. ”

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

"I won't talk about the results of the mathematical modeling competition, you must have heard of it. In his sophomore year, he was able to build a model based on the experimental data I provided, and extrapolate the mechanical properties of the product based on the data collected by the FTIR spectrometer. How much technology is in this, you can figure it out for yourself. ”

After hearing this, not only Zhang Fan, who asked the question, but also the other two graduate students in the office also showed a moving look on their faces.

It's nothing to be able to calculate materials science, and now many experiments in materials science will use first-principles calculations, especially after Jin Dae came out of the demon of Lu Zhou, even if they are not engaged in this direction, they now understand a little bit.

But it's terrifying that sophomore year can do that.

As for what higher education society cup......

For these salted fish, it is very satisfying to be able to win a national award in the digital simulation competition, whether it is the first or the second.

Thinking that his junior brothers were so awesome, Zhang Fan couldn't help but start to reflect on what he was doing in his sophomore year.

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 his students' faces, Professor Lee guessed what they were thinking, and just smiled and shook his head.

"Don't be envious, that kid is a genius in mathematics, and it didn't take long to solve a world problem in the field of number theory not long after he won the Higher Education Society Cup...... It seems to be asking Zhou to guess something. You haven't met him, and you probably don't feel how strong his mathematical instincts are. To put it simply, I am grateful that you can draw a picture of a set of data thrown to you, but if you throw it in his hand, he can conjure flowers for you. ”

Several students looked at each other.

They obviously didn't understand what kind of sassy operation Professor Li Rongen was talking about.

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

"Professor, why did you say that Professor Lu went to study superconducting materials? Does this thing have any industrial applications? ”

Li Rongen: "He is not necessarily researching this because of the prospect of industrial application, but if you have to talk about the prospect of industrial application, its application prospect may be much greater than you think." ”

Pei Qing was slightly stunned and wondered: "Is the market for superconducting materials so big?" ”

Professor Li Rongen smiled and shook his head: "It's not just about superconductivity. ”

Hearing this, Zhang Fan was also stunned: "Not just superconductivity? ”

"If you don't understand, read the paper again and you'll understand. What does the presence of Mott insulators mean that graphene can be 'on' or 'off' under certain conditions? Need I say more? ”

Pei Qing's expression was slightly moved: "...... Semiconductor? ”

Professor Li Rongen nodded approvingly, "Correct." ”

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

However, it is well known that graphene does not have a bandwidth, resulting in graphene electronics remaining highly conductive at any gate voltage and not being able to shut down completely, thus limiting its application in electronic devices.

However, the peculiarity of Mott insulators leads to the fact that when a gate voltage is applied, the electrons in the graphene superlattice can pass through the initial insulation state quickly, as if there is no resistance.

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

Just by using this layer of Mott insulators, it is not necessary to achieve a low temperature of 101K in the whole system to achieve the superconductivity transformation of the entire material.

Therefore, the significance of this paper is not only the application in the field of superconductivity, but also the research of graphene semiconductors has also opened up a new platform.

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, which is sold at a price, is still too wasteful to use for power transmission or something, but it is acceptable to use it in electronic products.

At this moment, the browser in the taskbar at the bottom of the desktop suddenly flashed.

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

When he saw this email, he couldn't help but be slightly stunned, and then a relieved smile appeared on his face.

"This kid didn't forget me."

Invitation to the Nobel Prize ceremony.

He had planned to watch the event on TV, but he didn't expect to have the opportunity to go there......
