Institute of Materials Technology, Chinese Academy of Sciences,

Graphene Research Laboratory.

The three top students from the Department of Condensed Matter Physics of Fuda have adapted to the working environment here. As for why they came to work here, the three of them are full of infinite gratitude to Xu Mang. They never thought that they would be able to work here.

However, they also encountered a lot of troubles. Facing this magical graphene, the three top students from Fuzhou University were completely speechless.

"what to do?"

"There's no way around this!" One of the girls said helplessly: "We don't have the ability like Professor Xu. The superconductivity of graphene has been almost completely studied by him."

"What should we do?" One of the boys said helplessly: "Graphene has more than just the hidden property of superconductivity. We can explore other properties based on the characteristic structure of graphene."

""

"Other abilities are easier said than done." Another boy smiled bitterly: "I heard that Professor Xu spent three months just to find the superconducting ability of graphene. We don't have his intelligence. If we spend time at the expense of

, I guess three years.”

After hearing what the boy said, the girl retorted on the spot: "Three months? How could it be three months? Who did you listen to?"

"The rumors outside say so, including many people in this institute." The boy said: "And I also asked a lot of people, and almost all of them had the same story. Professor Xu had three things to do before he discovered the superconducting properties of graphene.

I have been researching it for months, but I don’t believe it at all.”

""

""

Faced with this lie, I was speechless. Although I don’t know why everyone in this institute spoke in unison, one thing is very clear. Professor Xu has never studied graphene before. He is a man like the wind in the school.

, how can you 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 are also responsible for cultivating relevant talents. Currently, there are a total of fifteen master's students in the Graphene Institute laboratory.

current,

The main research project of this laboratory is about graphene's controllable insulator, and this decision was based on a wonderful conversation between the three people. Since graphene was discovered fifteen years ago, it has attracted much attention because of its excellent electrical, mechanical and other properties.

.

Graphene electrons move fast, the effective mass of electrons is small, and the interaction between electrons is also small. Therefore, it has excellent electrical conductivity and is widely used in a series of equipment such as electronic devices. However, the only one among the three

The girl asked, if graphene, which has excellent conductive properties, can be tuned into an insulator, what disruptive impact will it have?

In this regard,

The three set up a project to study graphene-controlled insulators, and the project was quickly approved. However, such a fast approval resulted in unprecedented trouble.

The conductivity of materials is generally explained by the energy band theory. When electrons fill the middle of the energy band, the material is a conductor. On the contrary, if the electrons fill the band gap between the energy bands, the material is an insulator.

But they found that electrons simply could not fill the band gap between energy bands, so the project became somewhat difficult.

Three whole weeks,

Everyone is still confused when facing this problem, but there have been several accidents. Due to an accidental mistake, graphene became an insulator. Only that time the equipment that recorded the data crashed, resulting in the data not being recorded.

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

"Xiao Zheng, why don't we ask Professor Fan?" a boy said.

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

"Um!"

The words fell,

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

The Professor Fan the boy mentioned was Fan Zhilong, a condensed matter physics major in the Department of Physics at Fuzhou University. As a professional in this field, he might be able to provide some help.

soon,

The emergency call went through.

"Professor Fan," Xiao Zheng said helplessly: "We encountered a big trouble and were 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 it was because Xu Mang asked him to find these three people. If the three of them were very bad,

Ideally, the first person to be embarrassed would be Fan Zhilong.

"We are studying the controllable insulating state of graphene, but we have encountered a big problem." Xiao Zheng said: "I remember that you have done related research on the controllable insulating state before. I wonder if you have relevant experience to teach us."

Controllable insulating state of graphene?

This is tricky!

Fan Zhilong was speechless. Graphene is not the same as other materials. There is no connection at all.

"this"

"Xiao Zheng tells you the truth, the properties of graphene are different from other materials." Fan Zhilong said seriously: "You should know and I have too little research on graphene, so I'm afraid I can't be of much help."

"well"

"Then it's over." Xiao Zheng sighed, and suddenly she thought of a savior, a top-level existence, and hurriedly said: "Professor Fan, why don't you help me communicate with Professor Xu? Can you help me, no?

We need him to help us solve all the problems, we want a theory that can support insulation."

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

Xu Mang

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

Speaking of Xu Mang,

Fan Zhilong has not seen Xu Mang for three days. He only knows that he has been in the laboratory recently, and it was in the afternoon that Xu Mang waited for others to leave before he went to the laboratory. Then in the morning, when others arrived, he left in a hurry. No one knew

What is he 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, you will probably have to wait a few days." Fan Zhilong said, "He has been very busy recently, and even I can't find him."

"oh"

"Then" Xiao Zheng knew that she shouldn't ask the next question, but she was too curious and asked cautiously: "What earth-shattering things is Professor Xu doing again?"

"I can only tell you three words about graphene!"

The words fell,

Xiao Zheng took a breath, Professor Xu is going to take action again?!

"alright."

"Just wait a few days." Fan Zhilong said and hung up the phone.

this

Started again?

Xiao Zheng froze on the spot, still in the digestion stage of the news he had just received.

Just returned to the laboratory,

The two boys were hurriedly surrounded by her and kept asking questions.

"What do you say about the situation?"

"Has the problem been resolved?"

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

And this result,

It was a big blow to the two boys, but one of them didn't give up and asked Xiao Zheng: "Then have you asked 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 is very busy recently and has no time for the time being."

Just when the two people's faces were ashen, Xiao Zheng said hurriedly: "But it's soon. Professor Xu is currently studying graphene. It will only take a few days before he will be free."

"???"

"???"

The two of them were stunned for a moment, looking at Xiao Zheng in disbelief.

"right!"

"Just a few days." Xiao Zheng added after seeing the expressions of the two people.

"No!"

"Ahead!" A boy said in horror: "Professor Xu is studying graphene again?"

"Um!"

"I guess the results will come soon." Xiao Zheng said.
