After the frost, the weather in Jin Ling became a lot colder. Even though it was not winter yet, it was colder than winter.
At this moment, in an office in the physics department of Jin Ling University, the vacuum flask on the desk was steaming.
Professor Lee Yong-eun was sitting at his desk. He was drinking hot tea as he browsed through the conference information on his computer.
It was almost the annual MRS Autumn Conference, and the theses that were going to be presented at the conference had been released.
Regardless of whether or not one had time to go to the conference, the top materials science summit was something that anyone in the materials science world would pay attention to.
Judging from the trend of thesis submissions, graphene research had shown explosive growth this year.
The most eye-catching one was undoubtedly the research paper on graphene superconducting materials.
101K！
This number caused a sensation in the materials science world; it could be described as a tsunami.
If one were to rank the theses with the highest number of downloads, then this thesis, which was posted on the official website after the deadline, would rise to the top three at an incredible speed.
Even though Lee Yong-eun was not in the field of superconducting materials, and he did not even know much about graphene materials. His main research area was carbon nanotubes, this did not prevent him from understanding the thesis and understanding how nutty it was …
Professor Lee Yong-eun read the thesis from beginning to end. He put down the thesis and could not help but exclaim.
"Amazing."
Graphene superconducting.
This concept was an unattainable dream a few years ago. He did not expect that in just a few years, it would go from a theoretical level to an applied level.
Not just that, but from the content of the thesis, the 101K superconducting transition temperature did not reach the limit.
In theory, as long as the graphene carrier concentration continued to increase, this number could be higher … Of course, this sounded easy, but it was definitely not easy to do.
Regardless, anyone in the field of copper oxide superconducting materials would probably start to doubt their lives after reading this thesis.
After all, it took them half a century to raise the critical temperature of superconducting materials to around 125K. Graphene's advantages in plasticity and engineering performance were more than enough to beat it.
It seemed that Professor Lu was no longer satisfied with the lithium battery field.
Batteries, superconducting, what's next?
Professor Lee Yong-eun was only curious about one thing. What was this guy planning to research next?
It seemed that as long as it was a domain that he had set his eyes on, he would eventually overturn it.
Lee Yong-eun wasn't the only one who was reading this report. His PhD and master's students were also reading it.
The doctor named Zhang Fan adjusted his glasses and couldn't help but ask, "Professor, when you took God Lu to do experiments, what kind of person was he?"
Professor Lee Yong-eun smiled.
"What kind of people? Other than genius, I don't know how else to describe him. "
Professor Lee Yong-eun paused for a second and recalled the past.
"I won't talk about the results of the mathematical modeling competition. I'm sure you've heard about it. In his sophomore year, he was able to build a model based on the experimental data I provided and calculate the mechanical properties of the product based on the data collected by the Fourier infrared spectrometer. You can figure out how much technology is involved in this. "
Zhang Fan wasn't the only one who asked the question. The other two graduate students in the office were also impressed.
It wasn't a big deal to know computational materials science. A lot of materials science experiments used first-principle calculations, especially after Jin Ling University had a genius like Lu Zhou. Even if they weren't in this field, they still knew a little bit about it.
However, being able to do this in his sophomore year was terrifying.
As for the Higher Education Society Cup …
For people like them, being able to win a national prize in a mathematical modeling competition was enough.
Zhang Fan couldn't help but reflect on what he had been doing during his sophomore year when his junior brother was already so awesome.
However, other than the name of his ex-girlfriend, he couldn't remember anything.
Professor Li Rongen looked at the expressions on his students' faces and guessed what they were thinking. He just smiled and shook his head.
"Don't be jealous, that kid is a mathematics genius. Not long after he won the Higher Education Society Cup, he solved a world-class number theory problem … I think it's called Zhou's conjecture or something. You guys haven't seen him before, so you might not know how strong his mathematical intuition is. Simply put, if I throw a set of data to you, I'd be thankful if you could even draw a graph. However, if you throw it to him, he can make a flower out of it. "
The students looked at each other.
They obviously didn't understand what Professor Lee Yong-eun meant by making a flower out of it.
While they were talking, Pei Qing finished reading the thesis and looked away from the computer screen.
"Professor, why do you think Professor Lu is researching superconducting materials? Does this thing have any industrial applications? "
Li Rongen: "He's not necessarily researching this because of the industrial application prospects, but if you really want to talk about the industrial application prospects, then it's probably much bigger than you think."
Pei Qing paused for a second and asked, "Is the market for superconducting materials that big?"
Professor Lee Yong-eun smiled and shook his head, "It's not just superconducting."
When Zhang Fan heard this, he asked, "Not just superconducting?"
"If you don't understand, read the thesis again. The existence of the Mott insulator means that graphene can be 'on' and 'off' under certain conditions. What does this mean? Do I need to say more? "
Pei Qing said, "… Semiconductors?"
Professor Lee Yong-eun nodded and said, "Correct."
Graphene had a high load carrier mobility, so it had broad application prospects in the field of electronic devices such as transistors.
However, it was well known that graphene had no bandwidth, which resulted in graphene electronic devices maintaining high conductivity under any voltage. It could not be completely shut down, which limited its application in electronic devices.
However, due to the special nature of the Mott insulator, the electrons in the graphene superlattice could quickly pass through the insulated state when a voltage was applied to the material. It was as if there was no resistance.
There was no doubt that this was an "on" state.
Just by using the Mott insulator's properties, there was no need to reach a low temperature of 101K in order to achieve the superconducting transition of the entire material.
Therefore, the significance of this thesis was not only in the field of superconductivity, but it also opened up a new platform for graphene semiconductor research.
Not only would the energy industry be interested in the MRS Conference, but major electronics manufacturers would also follow up on this research.
After all, graphene was sold in grams, so it was too wasteful to use it for power transmission. However, it was acceptable to use it in electronic products.
At this moment, the taskbar browser at the bottom of the desktop suddenly flashed.
When Professor Lee Yong-eun saw that there was a new email notification, he opened his email.
When he saw this email, he could not help but be stunned for a moment, then a gratified smile appeared on his face.
"This kid didn't forget about me."
