Based on his previous discoveries, Xu Mang imagined adding another layer of graphene to the double-layer graphene to see if any changes would occur. Of course, it still needs to be proven theoretically, at least through a process.

but

Xu Mang soon discovered that the rotation angle of three-layer graphene is theoretically impossible to achieve superconductivity, because the characteristics of the double-layer magic angle are destroyed, so the superconductivity of three-layer graphene seems to become non-existent.

This did not surprise Xu Mang. Since the rotation angle was impossible, he would find other ways to try to achieve superconductivity in theory.

Xu Mang thought for a while. The most common and stable three-layer stacking method in nature is aba. The other two stacking methods are aaa and abc. Is it possible to find three-layer graphene by studying three different stacking methods?

Is superconductivity theoretically possible?

Maybe

after,

Xu Mang opened the model making software on the computer and built models for three different stacking methods. This process did not take much time. He had already accumulated a lot of experience when studying double-layer graphene superconductivity.

experience.

Comparing the three different stacking methods, Xu Mang had the illusion that different stacking methods might affect the energy band structure, and the energy band results determine many characteristics, such as its electronic and optical properties.

"It's interesting!" Xu Mang's interest was aroused, but for now this is just a guess, a kind of fantasy data after analysis from the model, which still cannot escape mathematical calculations and experimental verification.

"Hello?"

"Director Fang!" Xu Mang made a call to Director Fang of the Department of Physics. Although their offices were adjacent to each other, Xu Mang felt that there was a sense of ritual in making such a call.

""

"Xu Mang, my office is right next to yours. Can't you just walk two steps?" Director Fang was so helpless. This guy was also too lazy to describe in words. He was obviously right next door to him, so he was so helpless.

I don’t want to walk such a distance, it’s really a new level of laziness.

But this is not the most irritating thing. The most irritating thing is that this kind of person can make breakthroughs in the field of physics every now and then, and his discoveries are shocking to the world. Xu Mang's appearance is a big surprise to some people.

Not very friendly.

"Haha" Xu Mang smiled awkwardly but politely: "It feels more formal this way."

"Okay, okay." Director Fang urged hurriedly: "What exactly is going on?"

"Does our Department of Physics have angle-resolved photoelectron spectroscopy equipment with nanoscale spatial resolution?" Xu Mang asked: "I suddenly came up with a new idea, but this idea is hindered by the need for this kind of equipment to explore."

"Nanoscale"

"There are not many in the country, we don't have it." Director Fang said seriously: "As far as I know, Nanjing University and Tsinghua University have such equipment."

"Nanda University and Qingdao University?" Xu Mang was stunned for a moment, and said with a painful look on his face: "I have a grudge against these two schools. There is competition in gravitational wave detection, so I don't think they will lend it to me.

"

"Then there's nothing I can do." Director Fang sighed: "How about I ask you again?"

"Um!"

"Try to be the kind of school that has not participated in the joint gravitational wave detection experimental project, otherwise the probability of being able to borrow equipment is not very high." Xu Mang said seriously: "Most of the C9 alliance has participated, only Jiangsu University and Harbin University

, Xi’an Jiaotong University was not involved.”

"oh!"

"Jiang Da has such equipment." Director Fang suddenly said: "You are familiar with Jiang Da, so why not ask."

"oh"

hang up the phone,

Xu Mang hurriedly called Director Lin of the Department of Physics at Jiangsu University.

When I was about to dial the number,

Someone knocked on the office door.

"Please come in!"

moment,

A student walked in, but Xu Mang didn't recognize him.

"Who are you?" Xu Mang looked at the student curiously, with the word 'confused' written all over his face.

"Hello, Professor Xu. I am Meng Jie, a junior student in optics." The student named Meng Jie said awkwardly, "Professor Xu, I wonder if you are free now?"

"For now."

"Tell me what you have to say." Xu Mang nodded.

result,

The next second,

A mysterious bank card appeared on Xu Mang's desk.

""

""

Suddenly,

There was silence in the office.

Xu Mang finally understood that this student is a talent. Although his methods are a bit simple and crude, his courage is not ordinary. Although his face is not at the top level for the time being, he is thicker than most people.

, I have to say that his guy is quite good.

Xu Mang didn't want to admit it, but the fact was that this type of students succeeded in society much faster than ordinary people.

well

I recall that back then I tried my best to give gifts to teachers, but in the blink of an eye, the ones who used to give gifts became the ones who were given gifts.

"Ahem!"

"What do you mean?" Xu Mang asked curiously.

"It's not interesting, it's just interesting." The student said calmly.

"You're quite interesting here." Xu Mang said.

"Actually, it doesn't mean anything else," the student said.

Under the enigmatic exchange, Xu Mang suddenly asked: "What do you mean?"

"Professor Xu"

"My postgraduate entrance examination has passed the preliminary examination, and now it is in the re-examination stage. I heard that you understand." The student said cautiously: "My father's surname is also Meng."

Xu Mang was speechless. Isn't this nonsense? Could it be that your father's surname is Xu?

"oh"

"How about you go find Director Fang?" Xu Mang thought of a way and pushed him to Director Fang.

"Professor Xu"

"I just came from Director Fang's office." The student said, "Director Fang asked me to come to you. He said that this matter is under the control of the deputy director."

Damn it!

Nima

No wonder no one wants to compete for the position of deputy director, relationships are easy to get into!

Xu Mang was so angry. He thought he had taken advantage and got the deputy director for no reason, but now he thought about how there was no such thing as a pie in the world. At that time, he didn't consider why the deputy director was always vacant.

.

Sure enough, it doesn’t work with side effects, such as side effects.

"oh"

"I understand." Xu Mang nodded, responded casually, pushed the bank card on the table towards him, and said, "Take this card."

at this time,

The student was a little panicked, which meant that things were not in place yet!

"Professor Xu?"

"I" the student reluctantly took the card, walked out silently, stopped at the door, turned around and said, "Professor Xu, my father is Meng Qing."

The words fell,

Closed the office door.

"Meng Qing?"

"Who is it?" Xu Mang really wanted to know who this Meng Qing was. With this idea in mind, he searched the Internet and found that this man named Meng Qing was really a character, but that was it. There was nothing special about him.

at.

well?

What do I want to do?
