Scholar’s Advanced Technological System

After the frosting, Kim Ling's weather became much colder, though not yet in winter, but rather colder in winter.

At this moment, there is a mist on the insulation cup at the work desk in the campus of Jinling University, at some office of the hotel.

Professor Ron Lee sits at his desk, drinking hot tea and browsing conference information on his computer.

The annual MRS Autumn Meeting is soon to take place, and papers to be presented at the meeting have been released.

Whether or not you have time to go to the scene, this top-level summit of material academia is something that any material person will be interested in.

Based on the trend of paper submission, this year's study of the direction of graphene shows a well blown growth.

And the most striking of these, undoubtedly, is the paper on the study of graphene superconducting materials.

101K!

The surge caused by this number in the material sciences is simply described by the tsunami.

If sorted by the highest number of downloaded papers, this paper, which was posted on the official website after the deadline, is rising to the top three at an incredible rate.

Although Lee Rong Eun is not in the direction of making superconducting materials, he doesn't even know much about graphene materials. He mainly researches carbon nanotubes, but this does not prevent him from understanding what is discussed in the paper and experiencing the bullshit in it...

Reading the paper from beginning to end, Professor Lee Rong-en let go of the paper in his hand and couldn't help but feel emotional.

“Awesome. ”

Graphene superconducting.

This concept was still an unreachable dream a few years ago. I had no idea that in just a few short years, a breakthrough had been made from the theoretical level to the application level.

Not only that, from what is described in the paper, this 101K superconducting transition temperature has not reached its limit.

Theoretically, as long as we continue to increase the carrier concentrations of graphene, this number can be even higher... which, of course, seems easy to say, but certainly not easy to do.

Anyway, people who do research on copper oxide direction superconducting materials may be suspicious of life after seeing this paper.

After all, it took them half a century to raise the critical temperature of the superconducting to near 125K. Graphene's advantages in terms of plasticity and engineering performance are sufficient to destroy it.

It seems that Professor Lu is no longer content with turning the lithium battery field upside down.

Battery, superconductive. What's next?

Professor Lee Rong-eun is curious about one thing right now. What is this guy going to study next?

It seemed that as long as it was an area he was targeting, it would eventually be subverted by him.

Also watching this report is not only Lee Rong-eun, but also his PhD and Master's students.

Hearing the professor's emotion, the doctor named Zhang Fan pushed his glasses, unable to hold his curiosity in his heart, and asked, “Professor, what was he like when you brought Lu Shen to the experiment? ”

When he heard the question, Professor Lee Rong-eun laughed.

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

After a pause, recalling the original past, Professor Lee Rong-eun continued.

“I'm not going to say anything about the mathematical modeling contest. You've probably 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 Fourier Infrared Spectrometer. How much technology is in there? Think about it. ”

After hearing this sentence, not only Zhang Fan asked the question, but the other two graduate students in the office also showed a moving face.

Computational material science is nothing. Many experiments in material science now use the first principle of calculation, especially after Kim Dae came out of the evil of the Ark, even if they didn't do this direction, they now know a little bit.

But sophomore year can do it. It's horrible.

As for what Higher Education Cup...

For them salted fish, it was satisfying to win a prize in the Digital Model Competition, be it First or Second Nations.

I can't help but start thinking about Zhang Fan, thinking about what he was doing in his sophomore year.

But for half a day, he couldn't remember anything but his ex-girlfriend's name.

Seeing the look on the faces of his students, Professor Lee Rong-eun guessed what they were thinking and just shook his head with a smile.

“Don't be jealous, the kid is a mathematical genius. Shortly after he got the Higher Education Cup, he solved another world problem in mathematics... like calling Zhou Shi's guess or something. You haven't seen him, you probably don't feel how strong his mathematical instincts are. Simply put, a set of data is thrown at you, and you can draw a diagram, and I'm thankful for it, but it's thrown in his hand, and he can turn you into a flower. ”

Several students face each other.

They obviously didn't understand what Professor Lee Rong-eun said about turning into flowers was actually a fussy operation.

In the talking room, Pei Qing, who had never spoken, also finished reading the paper and removed his gaze from the screen.

“Professor, why did Professor Lu go to study the superconducting material? Does this thing have any prospects for industrial applications? ”

Li Rong-en: "He doesn't necessarily study this because of the prospects for industrial applications, but if you have to say, the prospects for industrial applications are probably much bigger than you think. ”

Pei Qing stunned slightly, wondering: “Is the market for superconducting materials this big? ”

Professor Lee Rong-eun shook his head with a smile: “It means more than just superconducting. ”

Upon hearing this, Zhang Fan also stunned: “Not just superconducting? ”

“If you don't understand, you can read the paper again. What does the presence of Mott insulators mean that graphene can be ‘turned on' or ‘turned off' under certain conditions? Do you need me to say more? ”

Peiqing Divine Microscopy: “… Semiconductor? ”

Professor Lee Rong-eun nodded in praise of the location, "Correct. ”

Graphene has broad application prospects in the field of electronics such as transistors due to its high charge carrier flow rate.

However, it is well known that graphene does not have bandwidth, which leads to the graphene electronics remaining highly conductive at any gate voltage and cannot be completely closed, thus limiting their application to electronics.

However, the particularity of the Mott insulator results in electrons within the graphene superlattice passing quickly from the initial insulation state, as if there was no resistance, with the material being subjected to a gate voltage.

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

Simply utilizing this layer of the Mott insulator, it is not necessary to bring the entire system to a low temperature of 101K to achieve a superconducting transformation of the entire material.

Therefore, the significance of this paper is not only applied in the field of superconducting, but the study of graphene semiconductors also opens up a brand new platform.

In anticipation of the MRS meeting, not only the energy industry would be interested, but major electronics manufacturers would follow up on the research.

After all, something like graphene is too wasteful for electricity transmission, but it's acceptable for electronics.

At this point, the browser in the taskbar below the desktop suddenly flashed.

When he saw a reminder of a new e-mail, Professor Lee Rong-eun opened his e-mail address.

When he saw the e-mail, he couldn't help but dazzle and smile with relief on his face.

“The kid didn't forget me. ”

Invitation to the Nobel Prize Ceremony.

He was going to watch the event on TV, but didn't expect to have a chance to go to the scene...
