Chapter 797

Mordo,

Xu Mang and song Xiaoxi came to Xuyang Research Institute, and the intense work started. Of course, in order to work smoothly, Xu mang re optimized the list of members of the research group. At present, there are five members in the team for preparing quantum materials, and his team is full of nine people.

In the latest experimental work, in addition to the heterojunction formed by placing superconductor strips on the surface of quantum anomalous Hall insulator proposed in the theoretical model, Xu Manghai has prepared nanoscale superconducting probes with the same superconductor on the same device to characterize the contact between quantum anomalous Hall insulator and superconductor.

The differential conductance of superconductor and quantum anomalous Hall insulator under DC bias is measured by using superconducting nanoprobe structure. Of course, Xu mang will not participate in the experimental process. He needs the results of the experiment. Now he is waiting for a proof.

Whether the superconductor and the quantum anomalous Hall insulator can establish an almost ideal contact, if all the data prove that their conjecture is correct, then the next experiment can be continued, or the experiment will be overturned again.

Song Xiaoxi told Xu mang that after several days of the experiment and repeated tests, Xu could only quietly accept the time for a few days.

When he came home from work,

Xu mang had just put a bag of vegetables in the refrigerator. As a result, Yang Xiaoman came back with a lot of anger. Seeing her appearance, he knew that she must have been bullied again. However, he was full of curiosity about who bullied her.

"Wife?"

"What's the situation?" Xu mang asked curiously: "when I got home, I sat on the sofa sullenly, and I didn't watch TV... Was it bullied?"

"I'm so angry!"

"I ordered a piece of equipment last year and suddenly announced that it would not be sold to us today." "It's a $150 million device, mainly for Dad's company," Yang said with a small mouth and angry face

"In a word, mom, I've completely broken my skin with them. I'm going to raise the price in the American market." Yang Xiaoman said angrily: "really can't... Refuse all the demands of the United States of America and will not sell them to him. Whoever dares to sell them, I will terminate all contracts with him."

"Ah?"

"Why don't I know?" "What kind of equipment is it?" Xu mang asked with a confused face

"The mask is aimed at the exposure machine..." Yang Xiaoman took a look at Xu Mang and seriously said, "husband, can you make this kind of equipment? If you know the photoresist material first, it should not be a problem for the mask to aim at the exposure machine? "

"Er..."

"no!" Xu shook his head and said helplessly: "materials and equipment are two different concepts. Even if there is a mask aiming at the drawing of the exposure machine, we can't make it... This kind of precision equipment needs professional manufacturing equipment, but we lack this kind of high-precision manufacturing equipment."

Xu mang is also helpless. Before, he seemed to solve the problem of mask alignment exposure machine, but found that it could not be solved at all... The lack of precision equipment for manufacturing mask alignment exposure machine has been out of his ability.

"Alas..."

"what to do?"

"Damn America, it's getting in my way." Yang Xiaoman said angrily: "I really want to smooth this damned country from the earth. As long as the world has no them, world peace will be long ago."

On this point,

Xu mang especially agrees with Xiaoman's views, and he also thinks that it is necessary to check and level them, but... It is not possible at present.

"All right, all right." Xu mang sat beside Xiaoman, quietly hugged her into his arms, kneaded his pretty face, and said helplessly, "don't be angry... Some things are beyond our control. If we don't sell, we can't sell them. What else can we do?"

"I'm not convinced."

"We talked about it a year ago, but now if we say we don't sell it, we don't sell it." Yang Xiaoman complained to Xu Mang: "betray the truth..."

"after all, people are on the same front, and we are not in line with their values." Xu mang said helplessly: "you have mastered a lot of core technologies, and they are also annoyed... The world situation is not very stable now. Let's talk about it later."

Yang Xiaoman didn't speak with his mouth, and now he's in a mess... It's either a fire or a war. He glanced at Xu mang holding himself, and squeaked, "I'm very angry now, so I need you to give me some vitality."

Then he closed his eyes in silence and waited for Xu Mang's next move.

Looking at her expectant appearance, Xu mang knows that if she can't meet Xiaoman's requirements, she is likely to blow up his dog's head. This woman is unreasonable.

(* ￣ 3 (* ^ ▽ ^ *)

at night,

quietly,

Xu mang sat at the head of the bed, watched the news with a tablet, and understood the major international events. Looking at it, he thought it was meaningless. He opened the game and planned to bring the glory of the king. As a result, Xiaoman came back from the bath."Husband?"

"I found that I have grown tall recently." "I couldn't reach the shower before, but now I can," Yang said

"..."

"you are more than 20 years old, the bone line has healed long ago, and you can grow a fart!" Xu mang didn't get angry and said, "that's me moving down a little bit. Don't be full of doubts about your height. You are really short... Accept the fact."

Yang Xiaoman is so angry that he would like to kill this man. If you want to expose him face to face, can't you save face for me?

"Eh?"

"Why are you starting to cheat again?" Yang Xiaoman saw Xu mang playing a game, a white eye said: "on your level... Don't play games, harm others and yourself."

"Ah?"

"Xiaoman... You take me to fly?" Xu mang said with a smile: "take me to play two ranks."

Finally,

in the end, under Xu Mang's good words and bad deeds, Yang Xiaoman managed to take Xu mang to swim freely in the sea of victory. As a result, he went in with confidence and cried out. There was no way... It was too much food, and the food was too much to look at directly.

"What are you doing? How about the number of wechat steps? "

"Let's fight! I'll let you fight in a league! Did you hear that? You... You're back in town? "

"Get out of here!"

On this day,

on this day,

Xu mang returned to the Research Institute and came back to the laboratory after two days' absence. He felt a different kind of feeling and was very pleased to see everyone working hard. He quietly went back to his office, locked the door of the office, and then slept in it.

Before Xu mang falls asleep,

a sudden knock on the door wakes Xu mang. However, he opens the door and sees song Xiaoxi standing at the door with his materials.

"Something?"

"The experiment is done." Song Xiaoxi handed Xu mang a stack of data, seriously said: "Professor Xu, this is the experimental quantum abnormal hall insulator and superconductor heterostructure sample structure and electrical characterization data."

"This is the data used to characterize the contact between superconductors and quantum anomalous Hall insulators through superconducting nanoprobes." "Professor Xu... In our experiments, we have proved that the differential conductance of nanoprobes under DC bias conforms to the andriev reflection model, and the differential conductance at zero DC bias is nearly twice as strong as that at high DC bias," Song said

"You're right. There's a near ideal contact between superconductors and quantum anomalous Hall insulators." Song Xiaoxi said admiringly: "Professor Xu... What should we do next?"

"You go back to the office first."

"I'll let you know then." Xu mang said calmly.

"Well!"

Song Xiaoxi just walked to the door, turned to Xu Mang and said, "Professor Xu... Can I take a leave? I haven't met Weiwei before. She doesn't even know I'm in Mordor. "

"Oh..."

after Song Xiaoxi left, Xu mang checked Cao Cong's paper before. He found that half integer quantization and integer quantization conductivity platforms coexisted. However, in the data provided by song Xiaoxi, there was no integer quantization conductivity platform, but the semi integer quantum conductivity platform not only appeared in the specific magnetic field predicted by theory, but also appeared in the specific magnetic field predicted by theory In the whole hall curve.

Maybe this is just an accident, but we can break through it and find the conditions for it. It is also possible that this is not an accident, but a theorem.

At this time,

what Xu wants is more experimental results to verify a theoretical model, but it should start the day after tomorrow.

"It seems that..."

"chiral marjorana fermions do not exist." Xu mang frowns and studies the data report carefully. He has a feeling that the truth of the matter will be announced soon, and there will be a big avalanche in the physical world.

"Hello?"

"Chiang Suo?"

"Can you send me another 30 samples?" "I need more sample data to explain a physical model. At present... The results of the first experiment have been difficult to explain with the physical model predicted by chiral Majorana fermion theory," Xu said with a smile

"Of course, there may be contingency. I want to know whether it is accidental or inevitable." "There are a lot of things that can be studied," Xu said seriously. "It's a good exploration of anomalous Hall insulators and superconductors."

"Good!"

"I'll arrange it right away." Jiang Suo said earnestly.

...

in the afternoon,

in the afternoon,

Yang Xiaoman, Zhou Weiwei, song Xiaoxi and Lin qiongcheng were drinking afternoon tea together. They were all talking about beauty and cosmetics, but soon this topic involved Xu Mang, and then there was a large-scale flattery.

"Little man!"

"I never thought that your husband should be professor Xu mang." Song Xiaoxi said with emotion: "let me briefly describe my experience in these days... One word can be summarized, that is invincible! Maybe you don't think it's a big deal, but it's invincible to me. ""There is no experimental data, just based on the theoretical model to predict the existence of chiral Majorana fermions must have two prerequisites... This strength, I can only say invincible." Song Xiaoxi sighed: "Xiaoman... How can I find an excellent man like Professor Xu mang?"

Lin qiongcheng also looked at Yang Xiaoman curiously, his eyes full of longing.

In the face of their thirst for knowledge, although I don't want to admit it, the fact is that they chased him. The guy was beaten passively and all of them took the initiative. No third party can know the details.

"By charm!" Yang Xiaoman indifferently said: "it is he who chases me, clinging to me all day."
