Chapter 687

What just happened?

Is this manuscript a breakthrough in the limit theory?

They look at Xu mang with horror on their faces. There is fear in their eyes. Their faces are full of unbelievable expressions and a little at a loss.

The limit theory has puzzled researchers of two-dimensional materials all over the world for so many years. As a result, Professor Xu solved it in one night? How can this be possible? With so many people in the world spending so many years, it's not as good as Professor Xu's one night?

"Xu..."

"Professor Xu?"

"These... These white papers are the manuscripts of breaking through the limit theory in legend?" The glasses sister Xiaotao looked at Xu Mang in surprise, pointed to the manuscript on the table and asked, "are you sure this is the manuscript that breaks through the limit theory?"

Xu mang took out a bag of "fool's melon seeds" which had not been knocked out yesterday. He nodded with a smile on his face and said, "yes, this is the manuscript that broke away from the limit theory. You can have a look at it yourself. By the way, make me a pot of tea after reading it."

"..."

"..."

neither of them spoke. Xiaoliu opened the manuscript that Xu mang had lost in silence, but only looked at it for a moment. In an instant, the whole person fell into dementia, and the shock on his face became a little panic.

Atomic level?

This is the subversion of the Three Outlooks!

"Ah?"

"What expression are you looking at?" Xiao Tao looked at his colleagues with a confused face, and found that his expression changes a little rich. Before, he was still a little surprised. However, at this moment, he seemed a little nervous and frightened.

"You... You see for yourself." Liu Tao handed the manuscript to Liu Tao.

Taking this manuscript, Xiaotao also opened it for a look. For a while, he fell into the same situation as Xiao Liu, and was greatly afraid of the contents of this manuscript.

Two people brush brush brush to look at Xu Mang, looking at this one side knock melon seeds, while playing mobile phone, the man's face from time to time show the expression of stealing joy, one night... Just one night, it broke the limit theory in the history of materials.

How did he...

How did he do it?

"Professor Xu!"

"Don't knock on the seeds... Talk to us about how you broke away from the limit theory." Xiao Tao asked in surprise: "Professor Xu, don't knock... Really don't knock. Please tell us quickly, how can we find the limit at atomic level?"

"I wrote it on it."

"Don't you look at it at all?" Xu mang knocked melon seeds and asked curiously.

"..."

"..."

read it,

don't understand!

All of a sudden, they both looked embarrassed and bowed their heads. The content in them completely exceeded the scope they could understand. It was relying on pure theory and mathematics to explain a phenomenon in the micro world. I'm sorry... I really can't understand it.

"Er..."

"Professor Xu, we... We don't understand." Xiao Tao said with embarrassment: "we are learning materials, and you are totally from the point of view of mathematics and physics. Although we are not bad in physics, we are really powerless in the face of this level."

"Oh..."

"well, even if I said it, I guess you can't understand it." Xu mang knocked melon seeds calmly, raised his head and looked at Xiao Tao. He said seriously, "go and make a pot of tea for me. In the afternoon, we start to study the preparation technology."

"Yes

...

in the afternoon,

in the afternoon,

Xu Mang, Xiao Tao and Xiao Liu started their intensive research work, with the theory of breaking through the limit, and the rest was to develop a new preparation technology according to the theory. There are two preparation methods in the world, one is the stripping method... This method has won the Nobel Prize in physics, and can be done with simple adhesive tape, and the object is stone Graphene.

The other is epitaxial method, in which the growth of a single crystal layer on a single crystal substrate has certain requirements, and the crystal direction of the substrate is the same as that of the original crystal.

However,

soon, the three met with a dilemma. Although they knew that the critical point of thickness is atoms, and if the critical point is smaller than the critical point of atoms, the lattice of two-dimensional materials will collapse, but there is no such technology in the current technology.

Atom?

At this time, Xu mang thought of his own modified STM, scanning tunneling microscope.

However, this idea was eliminated by himself. If we use the scanning tunneling microscope, it is a waste of limited resources. If we want to make 10000 independent Perovskite Thin Films, it is almost impossible.

What to do?

It's all over again!

"Professor Xu?"

"Are we in the mire again?" Xiao Tao asked with a confused face.

"Almost."

Xu mang nodded and said calmly, "but don't panic... You can always come up with a solution, but I'm particularly curious about what kind of strange reaction will be produced by the combination of epitaxial technology and stripping method."“？？？”

“？？？”

Combination of the two technologies?

This is the first time I've heard of it.

"Professor Xu."

"You are the only one in the world who has this idea." Xiao Liu said with a smile: "these two technologies are completely independent. How can they be combined? Epitaxial technology is a vapor phase epitaxy process, while stripping method is a pure gift from nature, which is different."

"Is it?"

"I like to break the rules the most." "I think it can be done," Xu said seriously

Facing the stubborn Xu Mang, they just smile helplessly. This time, Xiao Tao and Xiao Liu dare not talk nonsense and are beaten in the face by Professor Xu. Isn't it very embarrassing?

"Come on

Let's use the small perovskite method to prepare Perovskite Thin Films Xu said solemnly, "you don't need to succeed, just get as close as possible and find the problem."

"Oh..."

"OK."

After they nodded, Xiao Tao asked curiously, "Professor Xu... What about you?"

"Me?"

"I supervise your work." Xu blankly one eye, not good spirit ground says: "my wife pays you salary."

The reason "..."

"..."

can not be refuted at all!

In one afternoon,

the progress was reliable, and almost all the experiments were completed in three hours. However, according to the calculation, the success rate was not even half of Chengdu, especially for Xiaoliu, which adopted the stripping method, the probability was 1%.

In this regard, Xu mang is not surprised, but Xiaotao and Xiaoliu are somewhat frustrated and can not accept this fact.

The calculation shows that the critical point of thickness is atom, but what's the use of this? Without the relevant technical support, the light breaks through the theoretical framework, but in the end nothing is achieved.

On the way out of work,

Xu mang has just stepped forward, and Xiaotao, a sister of glasses, finds Xu mang.

"Xu..."

"Professor Xu, I want to apply for transfer from the laboratory." Xiao Tao said cautiously, "Professor Xu... It's not that I don't want to take the responsibility, but I just bought a house..."

"..."

"don't wait a few days." Xu mang calmly said: "anyway, you are not short of these days, in case there is any great breakthrough?"

"Oh..."

just finished speaking,

before Xu mang had gone a few steps, Xiao Liu stopped him again, which was also the matter of applying for transfer from the laboratory.

This time,

Xu agreed and passed Xiao Tao's application.

"Alas..."

"the mortgage... Forced them to death." Xu mang shows a helpless expression.

At night,

at night,

Xu mang carefully broke away from Xiaoman's bear embrace, put on his coat and trousers, and left his bedroom in silence and went to his study.

Turn on the light,

sit in front of the computer and look at the data of the two reports. For a moment, I feel a little confused.

"System... How much is the exchange value of the preparation technology of atomic grade perovskite films?"

[exchange value of preparation technology of atomic grade perovskite material film: 1 (physical)]

[exchange value of preparation technology of atomic grade perovskite material film: 5000 (chemical)]

eh?

Chemistry?

No, chemistry has reached mastery level. How can you still need 5000 skill points?

Does it have anything to do with chemistry?

Xu mang looked at the two research reports repeatedly, not to mention... Really found the application of chemistry.

Pay!

Xu mang didn't want to do chemistry again, mainly because it was too much trouble. It was a waste of two days to come and go back and forth. It was not cost-effective to think about it.

In a flash,

Xu mang obtained all the contents of the preparation technology of atomic grade Perovskite Thin Films. After repeated studies, it was found that the so-called perovskite thin films could be synthesized by reactive molecular beam epitaxy based on water-soluble sr3al2o6.

The most important thing is that the films can be transferred to different substrates, especially crystalline silicon wafers and porous carbon films.

"I see!"

"By dissolving the buffer layer in water, millimeter sized single crystal perovskite oxide films can be released from the substrate." Xu sighed blankly. The world is so wonderful.

At the same time,

the headquarters of the

Physical Society of America.

Henry Millan came to the work place as usual. Since he got Xu Yang's result formula, the whole person was much more relaxed, but there was some confusion. Many people reflected to him that Xu Yang's structural formula was too complex and the calculation process was too much.In the face of this problem,

Henry Millan set up a simplified formula group, but after 24 hours, the progress of the group was zero, and there was no room for simplification. Every number and symbol of the group was particularly important.

Henry Mirren had just poured himself a cup of coffee when the phone rang and looked at the caller. It was one of his friends.

"Hello?"

"Miller?"

"Call me in the morning. What can I do for you?" Asked Henry Millan, smiling.

"You seem to be in a good mood today?" A rude voice came out, "I want to ask about the research data of Perovskite Thin Films. How is the progress in China? Xu mang must be very angry? "

In words,

is a burst of laughter.

"I think..."

"now Xu mang should be so agitated that he can't even sleep well. So many people have been trapped, and as a result, we have been punished." Henry Millan said with a smile: "in a word, in their country, it's called good will be rewarded, and evil will be rewarded."

However,

they did not know that

a storm was brewing.
