Fuda,

Department of Materials Laboratory,

The miserable Xu Mang was kicked out of the house by his wife to help her complete the immature self-supporting perovskite film technology. It is pitiful to think about it... In fact, all the theoretical technologies are quite complete, but the problem lies in the manufacturing.

Two-dimensional crystal films of some materials are easy to prepare, but it is more difficult when the chemical bonds of the three-dimensional lattice of the material are strong, because in most crystal materials, the chemical bonds between atoms or molecules are still isotropic and spontaneously form three-dimensional.

This makes it extremely difficult to create quasi-two-dimensional materials. The only feasible way to create ultrathin films of these materials is to deposit the film onto a flat surface of another base material and monitor the process in real time at the atomic scale, known as

epitaxial technology.

But...

Xu Mang felt that this technology had flaws. According to the information he obtained, this epitaxial technology was matured during the study of high-temperature superconducting material copper oxide in the 1990s. This copper oxide has layered properties.

structure, but the bonds between layers are very strong, so scientists use epitaxial technology to prepare thin films to study its superconductivity.

It stands to reason that perovskite oxides, as oxides, should be able to use this method, but the information provided by the United States shows that the preparation of self-supporting perovskite single-layer films is very difficult, and their success rate is less than 10%.

But this is indeed the most advanced planned research by the United States.

Xu Mang felt that he had been cheated...cheated miserably.

"well..."

Xu Mang was lying on the chair, crossing his legs, cracking melon seeds and flipping through the information on the table. He couldn't help but sigh: "Life... why are you always on the road?"

"Hello?"

"Professor Smith!"

"I was fooled by your American delegation." Xu Mang took out his mobile phone and called Professor Smith, and said angrily: "What kind of perovskite oxide film composed of strontium titanate and bismuth ferrite?

Just a piece of trash!”

"..."

"Well?"

"When did you change this technology?" Professor Smith looked confused. He knew that Xu Mang had taken away the aerospace engine technology and the THAAD anti-missile system, and there seemed to be no more behind.

How come there are suddenly more perovskite oxides strontium titanate and bismuth ferrite thin films?

"I used the material database technology to replace it. You were also present when I signed the contract. Don't tell me you forgot?" Xu Mang said seriously: "This can greatly reduce the time of material research. You Americans are making a lot of money. I

We all cried because of the loss!”

After Xu Mang's reminder, Smith thought that there was a second contract document when he signed the agreement. At that time, he thought they were together, but he never expected that other technical replacements had been made privately.

But there is one thing to say,

After being baptized by Xu Yang's structural formula, Professor Smith had an illusion about Xu Mang. This Nobel Prize winner in physics, who was famous for extorting European and American technology in the past, seemed to have changed his ways and become a good person.

"Xu Mang?"

"Have you experienced any shock?" Professor Smith asked curiously: "This is not your style at all. In my impression... you should have deceived us and suddenly given us so many benefits.

, I’m a little uncomfortable with it.”

"well..."

"In a Chinese saying, it's called...put down the butcher's knife and become a Buddha immediately." Xu Mang said helplessly: "Professor Smith...please help me find out, which bastard did this? I'm halfway through the research.

...You still have the nerve to say that it is the result of America’s advanced research in semiconductors.”

"All right!"

"Let me help you ask, right...Xu Mang?" Professor Smith asked seriously: "Is the Xu Yang structural formula you gave us the simplest one? Why do I feel... something is wrong?

?This is a lot of calculations!”

Xu Mang sighed and said helplessly: "I also want to have a formula structure like e=mc^2. A simple equation condenses the energy of the entire universe. Unfortunately, I can't do it... How about you sponsor me a little bit?

?Sponsored one trillion U.S. dollars, and I devoted the rest of my life to the process of simplifying Xu Yang’s structural formula.”

"..."

"Okay, stop daydreaming." Professor Smith smiled bitterly and said, "I'll ask you now."

"kindness!"

hang up the phone,

Professor Smith made a phone call to the head of the Physical Society, Professor Henry Millen.

"Hello?"

"Professor Henry, I just received a call from Xu Mang. Do you have another deal in private?" Professor Smith asked: "What material database is used to replace the synthetic thin film of perovskite oxide strontium titanate and bismuth ferrite?"

?”

"right!"

"This is a temporary addition." Professor Henry showed a smile: "Did he find a problem?"

"Found it."

"So you called me and asked who the bastard was who said this was America's latest semiconductor research and development technology." Professor Smith smiled bitterly: "It couldn't be you, right?"

Henry said calmly: "I don't know why Xu Mang took it so lightly. I can only say... he was careless."

"..."

"Recently I learned a sentence in Chinese called "When is the time to retaliate?" Professor Smith's Chinese was not standard, but it was generally understandable, and he later translated the sentence in English.

Henry Mirren was silent for a moment and couldn't help but said: "This is indeed my fault. I originally thought Xu Mang would notice it, but he didn't even look at it."

"That..."

"How about you give him the original information?" Smith asked.

"no!"

"How could such a thing happen?" Henry Mirren said with a smile: "It just teaches him a lesson. We in the United States are not easy to mess with."

hang up the phone,

Professor Smith was a little at a loss. It seemed that Xu Mang had been tricked.

After thinking for a long time, I decided to tell him the truth. After all, Xu Mang is also a member of the Princeton Astrophysics Association, and is also the vice president who will be nominated soon.

"Xu Mang..."

"Let me tell you something, the information in your hand is actually a defective product." Professor Smith said.

Xu Mang:@#￥%...!

People’s hearts are unpredictable!

I was actually deceived.

"I..."

"You...this..." Xu Mang was so angry that he hurriedly asked: "Can I change it?"

"cannot."

"I asked for you, you can't change...Xu Mang, just take it as a lesson." Professor Smith said: "I'm also wondering, why didn't you check it?"

Xu Mang is very conflicted. He can't say that he has a hard conscience and defrauded you of 10 billion US dollars.

"well..."

"Professor Smith, have you seen it now? I, Xu Mang, am indeed a kind person." Xu Mang said with a hint of sadness: "You actually treat me like this... Professor Smith, I am very sad now, and the consequences are very serious."

Smith:???

serious?

How serious can it be?

Xu Yang has already obtained the structural formulas, so no matter how serious it is, it can't be too serious, right?

"Be more careful next time."

"Oh... by the way, I will nominate you as the vice president of the Princeton Astrophysics Society. The organizing committee will review it at that time, but... don't have high expectations, there is a high chance that you will be kicked out."

Professor Smith said: "Because you are Chinese."

"..."

"Oh." Xu Mang responded casually and said calmly: "I'll hang up first."

snap,

Xu Mang hung up immediately.

Grabbing a handful of melon seeds, Xu Mang frowned while cracking them. Actually... this information is quite complete, but it is missing a preparation technique.

"Can't they?"

"I can!"
