Institute of Materials Technology, Chinese Academy of Sciences,

Graphene Research Laboratory.

Three high-achieving students from the Department of Condensed Matter Physics of Fudan University have adapted to the working environment here, and they are still full of infinite gratitude to Xu Mang for why they came to work here, and never thought that they would be able to work here.

However, they also encountered a lot of trouble, and in the face of this magical graphene, the three high-achieving students of Fuda University were completely speechless.

"What should I do?"

"It's... I can't find any way around it!" One of the girls said helplessly, "We don't have the ability of Professor Xu... The superconductivity of graphene has been almost studied by him. ”

"What should I do then?" one of the boys said helplessly: "Graphene is not only a hidden property of superconductivity, we can explore other properties according to the characteristic structure of graphene." ”

“...”

"Other abilities... Easier said than done. Another boy smiled bitterly: "I heard that Professor Xu spent three months just to seek the superconducting ability of graphene, and we don't have the same intelligence as him. Three years. ”

Hearing the boy's words, the girl retorted on the spot: "Three months? How can it be three months, who did you listen to?"

"That's what the rumors are out there, including a lot of people at this institute. The boy said: "And I also inquired about a lot of people, almost all of them are the same caliber, Professor Xu was studying three months before the discovery of graphene superconductivity, but... I don't believe it at all. ”

“...”

“...”

In the face of this lie, it is also very speechless, although I don't know why the people in this institute are unified, but one thing is very clear, Professor Xu has definitely not studied graphene before, he belongs to a man like the wind in school, how can he focus on one thing.

After a simple exchange,

The three of them started today's work, as researchers of this institute, while studying graphene, they also bear the responsibility of cultivating relevant outstanding talents, and there are currently a total of fifteen master's students in the laboratory of the graphene research institute.

current

The main research project of this laboratory is about controllable insulators of graphene, and this decision is based on a wonderful conversation between the three of them, since the discovery of graphene fifteen years ago, it has attracted attention because of its excellent electrical and mechanical properties.

Graphene has fast electronic movement, small effective mass of electrons, and small interaction between electrons, so it has excellent conductivity and has a wide range of applications in a series of electronic devices and other equipment, but the only girl among the three proposed that if graphene with excellent conductivity can be regulated into an insulator, what kind of subversive impact will it have?

In this regard,

The three of them set up a project to study graphene's controllable insulators, and the project was quickly approved, but such a fast approval speed was exchanged for unprecedented trouble.

The conductivity of a material is generally explained by the band theory, when the electrons are filled in the middle of the band, the material is a conductor, and vice versa, if the band gap between the bands is filled, the material is an insulator.

But they found that the electrons simply couldn't fill the band gap between the bands, so the project became somewhat difficult.

For three weeks,

Everyone is still very confused in the face of this problem, but there are also a few accidents, in an accidental mistake, graphene became an insulator, only that time the equipment that recorded the data crashed, resulting in the data was not recorded.

However, this process is extremely short-lived and cannot be applied at all.

"Xiao Zheng... Why don't we ask Professor Fan?" said one of the boys.

"Okay. The girl named Xiao Zheng nodded and said, "I'll call him now and ask about the relevant content." ”

"Hmm!"

Words fall,

The girl named Xiao Zheng left the laboratory in a hurry.

The professor Fan in the boy's mouth is Fan Zhilong, majoring in condensed matter physics in the Department of Physics of Fuzhou University, and as a professional in this area, he may be able to provide a little help.

soon

The emergency call went through.

"Professor Fan..."Xiao Zheng said helplessly, "We have encountered a big problem, and we have been stuck for almost three weeks. ”

"What trouble have you encountered?" Fan Zhilong was stunned for a moment, as a mentor who taught them in the past, he was still very concerned about the future of these three people, most of them were because these three people were asked by Xu Mang to find him, if the three of them were not ideal, the first one to be embarrassed was Fan Zhilong.

"We were working on a controllable insulation state of graphene, but we had a big problem. Xiao Zheng said: "I remember that you have done research on controllable insulation states before, and I don't know if you have relevant experience to teach us." ”

What is the controllable insulating state of graphene?

Now it's tricky!

Fan Zhilong was a little speechless, graphene is not the same as other materials, this has no connection at all.

"This..."

"Xiao Zheng will tell you the truth that the properties of graphene and other materials are not the same. Fan Zhilong said solemnly: "You should know... And I have too little research on graphene, I'm afraid I can't help much. ”

"Ugh..."

"That's the end of it. Xiao Zheng sighed, and suddenly she thought of a savior, a top-level existence, and hurriedly said, "Professor Fan... Can you help me talk to Professor Xu? Can you help me, we don't need him to help us solve all the problems, we want a theory that can support insulation. ”

Hearing Xiao Zheng's words, Fan Zhilong was even more helpless.

Xu Mang...

I'm afraid I don't have much time.

Speaking of Xu Mang,

Fan Zhilong hadn't seen Xu Mang for three days, only knowing that he had been in the laboratory recently, and it was only in the afternoon that Xu Mang went to the laboratory when others left, and then in the morning when others arrived, he left in a hurry, and no one knew what he was doing.

But...

It just so happens that he is the only one who knows what he is doing.

"If you want to find Professor Xu, it is estimated that you will have to wait a few days. Fan Zhilong said: "He has been very busy recently, and even I can't find him." ”

"Oh..."

"That..."Xiao Zheng knew that the next question should not be asked, but she was too curious, and asked cautiously, "What earth-shattering thing is Professor Xu doing?"

"I can only tell you three words... Graphene!"

Words fall,

Xiao Zheng gasped, this... Professor Xu is going to make a move again?!

"Alright. ”

"Just wait a few days. After Fan Zhilong finished speaking, he hung up the phone directly.

This...

Started again?

Xiao Zheng froze in place, still in the digestion stage for the news he had just obtained.

Just back in the lab,

The two boys were hurriedly surrounded by her and asked one after another.

"What does the situation say?"

"Has the problem been solved?"

Faced with his colleague's question, Xiao Zheng looked bitter and shook his head helplessly.

And as a result,

It was a big blow to the two boys, but one of them didn't give up, and asked Xiao Zheng, "That... Did you ask Professor Xu? I think only Professor Xu can help us solve this problem. ”

Xiao Zheng shook his head again: "I asked Professor Fan, and he told me that Professor Xu has been very busy recently and has no time for the time being. ”

Just when the two of them were facing ashes, Xiao Zheng hurriedly said: "But it's also soon, Professor Xu has been researching graphene recently, and it is estimated that it will only be a few days, and he will be free." ”

“？？？”

“？？？”

The two were stunned for a moment, and looked at Xiao Zheng with incredulous faces.

"Yes!"

"Just a few days. Xiao Zheng saw the expressions of the two and added.

"No!"

"Ahead!" said a boy in horror, "Professor Xu again... You're working on graphene again?"

"Hmm!"

"I guess it's going to be right away. Xiao Zheng said.

The two of them frowned, could it be the superconducting realm? The superconductivity of graphene, the magic angle is already its limit, it should be impossible to break through this way, it is possible that Professor Xu is studying other fields of graphene.

But... What exactly is the field?

meanwhile

Some department leaders of the Institute of Materials Technology of the Chinese Academy of Sciences are holding a meeting in the conference room to conduct an in-depth exploration and discussion on the future research direction, fund allocation, personnel regulation and control, and other issues.

"I think that in terms of funding, with the current expenditure trend of the institute, the graphene project is a big problem that we need to solve. A person in charge said: "We have invested too much in graphene, and the only success is with the help of others. Expenditures should be reduced. ”

"I agree!"

Another person in charge said: "Now that the world's graphene research field has entered a low period, and the field of superconductivity is even more unspeakable. ”

afterwards

Criticism of graphene is flooding, but their criticism is not groundless, and there are fewer and fewer voices about graphene at present, except after the explosive news a year ago, there has been no major turning point until now.

What's more, the world's research on graphene is decreasing, and many schools and research institutions were ambitious to enter this field, but now they have withdrawn from the circle significantly, and this field has almost entered a cold winter.

Wang Xiong, as the deputy director of the Institute of Materials Technology of the Chinese Academy of Sciences, feels powerless, and it is difficult to curb the trend of decadence unless someone stands up again and publishes heavyweight research in the face of this situation.

This person... I'm afraid it's Xu Mang.

But

He doesn't seem to want to continue working on graphene.

I have to sigh that this is a big loss.

afterwards

After several discussions, the result was to cut three-fifths of the research funds for graphene, and this part of the funds was allocated to other projects.

Then came this fierce battle for funds, but in this battle, only Wang Xiong did not participate.

End of the meeting,

Wang Xiong returned to his office, faced with the current situation, he could only reluctantly choose to accept, the original research institute's graphene project was specifically for the field of superconductivity, but the field of superconductivity was difficult, and finally adjusted the direction and expanded the scope of research.

Who would have thought that after expanding the scope, it would still face a huge challenge, and the whole project was not cut, which is really a blessing in misfortune.

midday

When Wang Xiong came to the cafeteria, he happened to meet three people who came to work from the Department of Physics of Fuzhou University.

"Xiao Zheng, Xiao Fang, Xiao Song, come and sit with me. Wang Xiong hurriedly greeted the three of them.

Looking at the three of them,

Wang Xiong asked curiously, "How has the research progressed recently?"

"Wang... The progress is not very good. Xiao Zheng said helplessly.

Wang Xiong nodded and said seriously: "It is said that the research institute just held a meeting and voted that the research funds for the graphene project should be cut by three-fifths. ”

“？？？”

“？？？”

“？？？”

This...

To add insult to injury!

The three of them looked confused, they were cut down so much, what else are they going to study in the future? Isn't this a slow death?

Facing the expressions of the three people at a loss, Wang Xiong said helplessly: "I can't do anything about this, you should know that your field has entered a low period, if you want to get a second glow, someone must stand up and publish heavyweight research papers in the field of graphene." ”

Then

Xiao Zheng, one of the three girls, said solemnly: "Wang Suo, let me tell you the news, Professor Xu is researching graphene, and there will be results that will shock the world soon!"

Wang Xiong was stunned for a moment, and asked with a frightened face: "You... Are you talking about Professor Xu, is that Professor Xu?"

"Yes!" Xiao Zheng said: "As soon as Professor Xu's side is over, I will immediately contact him to guide our research project, and I believe that under his guidance, our controllable insulation state will be successful!"

After hearing these words, Wang Xiong's shocked expression gradually became a little excited.

XU Mang,

He... He's finally back?!
