I really don't want to lie down and win

Cao Junhui knew what Xu Mang meant. It was estimated that the conditions were too harsh to realize the application, but it could change the way of research, and even change the future changes in this field.

but...

At present, Xu Mang has not completed superconductivity, so all this is still unknown.

"Professor Xu?"

"How did you achieve superconductivity?" Cao Junhui asked.

"Rotation angle."

"We found a theory that predicts that when two layers of graphene rotate, forming a certain angle will lead to new electronic interactions." Xu Mang said: "We studied this theory carefully and felt that this Physicists' predictions are true."

words fell,

Xu Mang showed off his latest research results.

"Director Cao, look!"

"Each carbon atom in single-layer graphene has four valence electrons, three of which form hybrid orbitals by mixing s orbitals and p orbitals, and form bonds with other carbon atoms, and the remaining electrons are in graphite movement in a vertical orbit."

"If the double layers are superimposed and the angle is reversed, a phenomenon occurs, the Dirac cone band hybridization effect, and an energy gap appears on the Dirac cone, so that the Fermi velocity at the Dirac point is renormalized."

words fell,

Xu Mang smiled awkwardly: "This is what we imagined."

"..."

"How did you come up with so many associations?" Cao Junhui asked.

"Simulation by model." Xu Mang said with a smile: "Imagination is important, but it is not as direct as model simulation. We used the quantum database to simulate the model, and found that when two layers of graphene are superimposed and rotated, A magical pattern emerges, a moiré, a ripple of light and dark."

"The moiré pattern is easy to understand. The superposition of two identical geometric patterns will produce such a pattern, but the appearance of the moiré pattern leads to a situation, that is, the expansion of cells." Xu Mang continued: "Not only that, because the superposition state, 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."

"so..."

"The peaks and troughs of the electronic density of states are formed."

words fell,

Xu Mang opened the model diagram and pointed to the model on it: "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 something that can be seen in reality.

Before this,

It seems to have come to a misunderstanding, and has been wandering in the mode of sandwiching calcium atoms in bilayer graphene, resulting in no progress in research progress.

As a result... When Professor Xu Mang Xu came, it seemed that this embarrassing situation had been opened.

Although they are all theoretical or model data, this is also an improvement.

"Is there any other data?" Cao Junhui asked.

"..."

"No more." Xu Mang shook his head, and said helplessly, "To tell you the truth, I'm not too sure. Although it is possible 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? Based on 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 he was overthinking.

along with,

After a few more brief exchanges, Cao Junhui left the laboratory.

"Hey!"

"Are you stupid?" Yang Xiaoman glared at Xu Mang: "What do you mean before the laboratory is closed? What do you make others think? You are too impulsive, but you are Professor Xu, why are you so impatient?" ?”

"what?"

"I...I'm telling the truth." Xu Mang said with a confused face, "It's true that the experiment can be done before the laboratory is closed."

"you!"

"Big idiot!" Yang Xiaoman sighed, and said bitterly: "I can't even imagine a future without me, how miserable your life is, and in your situation, I'm afraid someone beat you to death .”

This...

What kind of talk is this?

To be fair, life would have been colorful without you.

But ever since I met you, my life was so miserable that I was driven to death, not only scolded but also beaten...

at this time,

Yang Xiaoman slowly opened Xu Mang's hand, sat down on his lap, lay down in his arms, and said shyly, "Hurry up...I'm your student now, Professor Xu Hurry up to class!"

I...

you...

Nima!

Is this crazy?

Xu Mang's hair was numb when he heard Xiaoman's words, good guy... If this woman is going to go to heaven.

"Hey hey!"

"What's wrong with you?" Xu Mang said with a dark face, "It's impossible for me to fall in love with you, and I will go to jail anytime and anywhere, good guy... You are adding three more years 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 righteously, "Please go away!"

Yang Xiaoman: #￣￣#

idiot!

Stupid!
