The person who came was Cao Junhui, the head of the institute. At first, he came to see the situation, but saw such a heartbreaking scene. What is the situation of these two people? Does research need to be so flamboyant?
"???"
"???"
Damn it!
who is it?
Xu Mang and Yang Xiaoman looked at the middle-aged man standing at the door with dumbfounded expressions, and were dissatisfied with his appearance for no reason.
"I'm Cao Junhui, the person in charge of this research institute." Cao Junhui said helplessly: "Professor Xu... Yang... Researcher Yang, can you temporarily separate? I know you are a couple, but... .right?"
Whoops!
This Nima...so shameful!
Yang Xiaoman heard Cao Junhui’s words, a red glow suddenly appeared on his pretty face, and he hurriedly emerged from Xu Mang’s thigh, and said shyly: "Director Cao...this...not what you see. Actually Xu Mang is teaching me quantum mechanics."
"..."
Teach you quantum mechanics?
You don’t need to sit on someone’s lap to teach, right?
Cao Junhui was helpless, but because the other party was Yang Jian's daughter, he could only smile and said, "Study well, study well."
Words fall,
Cao Junhui walked to Xu Mang's side, glanced at the monitor curiously, and asked, "Professor Xu, what are you doing?"
"Calculate whether the Fermi velocity will be changed when the two layers of graphene rotate." Xu Mang said seriously: "We have almost found a way to superconduct graphene, but...I guess this method is useless. "
found it?
No way?
This...
Cao Junhui looked at Xu Mang in surprise, and hurriedly asked, "Professor Xu, are you sure you found it?"
"Ok!"
"You should have found it." Xu Mang nodded: "But don't be too happy. Even if you find the superconducting properties of graphene, in theory, it will be of no use...just like the realization of superconductivity in a potted chicken. It brings only a change in thinking, not a change in technology."
Cao Junhui knows what Xu Mang meant. It is estimated that the conditions are too harsh and the application cannot be realized, but it can change the thinking of research, and even change the future changes in this field.
but...
Xu Mang has not yet completed superconductivity, so all this is still unknown.
"Professor Xu?"
"How did you achieve superconductivity?" Cao Junhui asked.
"Rotation angle."
"We found a paper that predicted that when the two layers of graphene rotate, forming a certain angle will lead to new electronic interactions." Xu Mang said: "We studied this paper carefully and think this The physicist’s prediction is true."
Words fall,
Xu Mang presented his latest research results.
"Look, Director Cao!"
"Each carbon atom in a single-layer graphene has four valence electrons, three of which are combined with s orbitals and p orbitals to form hybrid orbitals, and bond with other carbon atoms. The remaining electrons are in the graphite Ene moves on a vertical track."
"If the double layers are superimposed and the angle is twisted, a phenomenon will occur, the energy band of the Dirac cone is hybridized, and an energy gap appears in the Dirac cone, so that the Fermi velocity at the Dirac point is renormalized."
Words fall,
Xu Mang smiled awkwardly: "This is what we imagined."
"..."
"How do you think of so many?" Cao Junhui asked.
"Rely on model simulation." Xu Mang said with a smile: "Imagination is important, but it is not as direct as model simulation. We used a quantum database to simulate the model and found that when two layers of graphene are superimposed and rotated, it will There is a kind of magic pattern moiré, a kind of light and dark ripples."
"The moiré pattern is well understood. The superposition of two identical geometric patterns will produce such a pattern. However, the appearance of the moiré pattern leads to a situation where the cell is expanded." Xu Mang continued: "It is not only that, because the superposition The upper and lower carbon atoms are completely aligned to form an AA arrangement; the upper and lower carbon atoms are staggered to form an AB or BA arrangement."
"such..."
"Formed the peaks and troughs of the electron energy state density."
Words fall,
Xu Mang opened the model diagram and pointed to the model above: "This is the model."
Cao Junhui looked at the model carefully, and through Xu Mang's explanation, he really found some clues. This is not theoretical data, but can be seen in reality.
Before that,
It seems to have come to a misunderstanding, and has been hovering in the mode of sandwiching calcium atoms in the double-layer graphene, resulting in no progress in the research progress.
The result... Professor Xu Mang Xu seemed to open up this awkward situation when he came.
Although they are all theoretical or model data, this is also an improvement.
"Any other data?" Cao Junhui asked.
"..."
"No more." Xu Mang shook his head and said helplessly: "Tell you the truth, I am not too sure, although there is a possibility in theory, but... who knows in reality."
Cao Junhui nodded, and after understanding the progress, he said, "Professor Xu? How long will it take to test the superconductivity of graphene? At your current speed."
"Before the laboratory is closed." Xu Mang said.
"..."
Cao Junhui didn't know if he was complaining, but it sounded like he was complaining, maybe because he was careless.
along with,
After a few brief exchanges, Cao Junhui left the laboratory.
"Hey!"
"Are you stupid?" Yang Xiaoman glared at Xu Mang: "What does it mean before the laboratory is closed? What do you make others think? You are too arrogant, but you are Professor Xu, why are you so uncomfortable? ?"
"what?"
"I...I'm telling the truth." Xu Mang said with a bewildered face: "You can indeed test before the laboratory is closed."
"you!"
"Big idiot!" Yang Xiaoman sighed, hating iron and steel, and said: "I can't imagine how miserable your life is without my future. Just like you, I'm afraid that you won't be beaten to death. ."
This...
What is this?
Reasonable without you, life is simply colorful.
But since knowing you, life is miserable and urging to death, not only to be scolded but also beaten...
at this time,
Yang Xiaoman drew back Xu Mang's hand and sat down on his lap. He lay down in his arms and said shyly: "Hurry up... I am now your student, Professor Xu. Hurry up to class!"
I...
you...
Nima!
Is this crazy?
Xu Mang's hair was tingling when he heard Xiaoman's words, good fellow... if this woman is going to go to heaven.
"Hey hey!"
"What's wrong with you?" Xu Mang said with a black face, "I was dealing with you, and I was going to go to jail anytime and anywhere, good guy...you have added three more to the three-year sentence. year."
Yang Xiaoman pouted, and said angrily: "It's not for you."
Picking up Xiaoman and putting it aside, Xu Mang said with a righteous expression: "Please go away!"
Yang Xiaoman: (# ̄~ ̄#)
moron!
Idiot!
There is no tacit understanding between lovers.
...
Cao Junhui returned to the office, thought about it for a long time, picked up the phone and called Wang Xiong.
soon,
Wang Xiong came to the office and said to Cao Junhui, "Old Cao, what's the matter?"
"..."
"I went to Xu Mang just now, and I decided not to terminate the graphene project." Cao Junhui said solemnly: "The research funding will continue to increase."
what?
Not only will it not be terminated, but also additional funding?
Wang Xiong was confused and asked curiously: "Lao Cao...what's your situation? Didn't this graphene project be terminated? Why is it suddenly decided not to terminate now? Continue to add..."
Halfway through,
Wang Xiong suddenly reacted and looked at Cao Junhui in horror.
"Xu..."
"Xu Mang succeeded?" Wang Xiong said in surprise.
"No!"
"But the progress is so fast that it is frightening." Cao Junhui said: "Xu Mang's point of view is supported both theoretically and model data. He is currently calculating...anyway, we can almost know the result these days."
So fast?
He... he's only two days, right?
"What method did he take?" Wang Xiong asked.
"Xu Mang found a paper and conducted research based on this paper." Cao Junhui said: "It seems to change the angle of the double-layer graphene superimposed state, how many degrees it turns, I don't know, this is not... Calculate."
Wang Xiong naturally understood Xu Mang's awesomeness, otherwise he would not be found, but he never expected the results so soon.
Superconductivity can be achieved when two layers of graphene are stacked together and rotated at an angle up and down?
That's too simple, right?
"I am afraid..."
"It's not as easy as we thought." Wang Xiong said: "There should be an extremely harsh additional condition. Based on past experience, it must be at least two Baidu below zero to achieve superconductivity."
"But no matter what, if you rely on changing the angle to achieve superconductivity, this will greatly promote the field of condensed matter physics." Wang Xiong said seriously: "It may produce a seismic chain reaction."
Cao Junhui nodded: "I am issuing an announcement to cancel the plan to terminate graphene."
soon,
Many people in the institute have seen the announcement that the termination of the graphene project has been cancelled. The reason is not yet known, but it is certain that the project has come alive again.
Faced with this situation,
Many scientific researchers are very dissatisfied. Many projects are waiting for money. The termination of the graphene project can save money and invest in other projects. As a result... now this project is resurgence.
Make sense,
This project hasn't made progress for a long time. Is it necessary to continue carrying it?
however,
Some people say that because Xu Mang's arrival has changed the current situation, Cao Junhui Director Cao had to sell his face.
gradually,
Some people resent Xu Mang.
At this point, Xu Mang and Yang Xiaoman felt it when they were having lunch.
"Ugh?"
"What's the situation?" Yang Xiaoman asked curiously: "Why do some people feel indifferent."
"I don't know." Xu Mang shook his head and said indifferently: "Whatever they do, I just need to do my own thing~EbookFREE.me~whatever they like to do."
"It won't be..." Yang Xiaoman lowered his voice and whispered: "You blocked the way of others? Originally the graphene project was going to be terminated, but Cao came here in the morning and saw Your latest achievements, cancel and terminate when you go back...causing other people’s projects to be stuck indefinitely."
Not to mention,
Xu Mang felt that Xiaoman was right. As long as there are people, there will be rivers and lakes, and there must be competition.
suddenly,
Xu Mang felt that his pressure had become so great that if all his theories were to fail, he couldn't imagine what the situation would be like.
