What just happened?

Is this manuscript a manuscript that breaks through the theory of limits?

The two of them looked at Xu Mang with horror on their faces, their eyes contained fear, and their faces were full of disbelief and a little overwhelmed.

Limit theory, which has plagued 2D materials researchers all over the world for so many years, has turned out that... The result was solved by Professor Xu in one night? So many people around the world spend so many years, why don't you Professor Xu spend one night?

"Xu..."

"Professor Xu?"

"It's... In these blank sheets of paper are the manuscripts of the legendary theory of breaking through the limit?" Xiao Tao, the glasses girl, looked at Xu Mang in surprise, pointed to the manuscript on the table, and asked, "You... Are you sure this is a manuscript that pushes the limits of theory?"

Xu Mang took out a pack of 'fool seeds' that he didn't finish yesterday from his handbag, nodded with a smile on his face, and said, "Yes... This is the manuscript that broke free from the theory of limits, so take a look at it for yourselves, by the way... Help me make a pot of tea after reading. ”

“...”

“...”

Neither of them spoke, Xiao Liu silently opened the manuscript that Xu Mang threw over, but just glanced at it, and in an instant... The whole person fell into dementia, and his face changed from shock at the beginning to a little panic.

Atomic level?

This is simply subverting the three views!

"Huh?"

"What kind of expression are you?" Xiao Tao looked at his colleague with a confused expression, and found that his expression changed a little richly, and he was still a little surprised before, but at this moment he looked a little nervous and panicked.

"You... See for yourself. Xiao Liu handed the manuscript to Xiao Tao.

After taking this manuscript, Xiao Tao also opened it and took a look, and for a while he fell into the same situation as Xiao Yanagi, and he had a great sense of fear about the content of this manuscript.

The two of them looked at Xu Mang together, looking at this man who was playing with his mobile phone while knocking melon seeds, with a snickering expression on his face from time to time, one night... In just one night, the limit theory in the history of materials was broken.

He...

How exactly did he do it?

"Professor Xu!"

"Don't knock melon seeds... Tell us how you broke free from the limit theory?" Xiao Tao asked with a look of surprise: "Professor Xu, don't stumble... Don't really knock it, tell us about it, how did you find that the limit is at the atomic level?"

"I wrote above. ”

"Don't you look at it at all?" Xu Mang asked curiously while knocking on the melon seeds.

“...”

“...”

Looked,

I don't understand!

Suddenly, the two of them lowered their heads in embarrassment, the content in it was completely beyond the scope of their understanding, this is relying on pure theory and mathematics, to explain the phenomenon of a microcosm, sorry... I really don't understand.

"Uh..."

"Professor Xu, we... We didn't get it. Xiao Tao said embarrassedly: "We are studying materials, and you are completely from the perspective of mathematics and physics, although in physics, we are not bad, but... In the face of this level, there is really nothing that can be done. ”

"Oh..."

"Forget it, I don't think you will understand what I said. Xu Mang knocked the melon seeds indifferently, raised his head to look at Xiao Tao, and said seriously: "Go and help me make a pot of tea, and we will start to study the preparation technology in the afternoon." ”

"Yes!"

...

Afternoon

Xu Mang, Xiao Tao, and Xiao Liu began intense research work, and had a theory that broke through the limit, and the rest was to study and think of the preparation technology according to the theory, and there are two preparation methods in this world, one is the peeling method... This method has won the Nobel Prize in Physics, and it can be done with a simple adhesive tape, and the object is graphene.

The other is the epitaxy method, which has certain requirements for growing a layer on a single crystal substrate, and the single crystal layer is in the same direction as the substrate, as if the original crystal has been extended outward.

however

Soon the three of them encountered a dilemma, although they knew that the critical point of thickness is atoms, and if it is less than the critical point of atoms, the lattice of two-dimensional materials will collapse, but in the current technology, there is no such technology.

Atom?

At this time, Xu Mang thought of his modified STM, a scanning tunneling microscope.

However, this idea was dispelled by himself, using a scanning tunneling microscope, which is a complete waste of limited resources, and if he wants to make 10,000 free-standing perovskite films, it is almost impossible.

What to do?

It's over!

"Professor Xu?"

"Are we stuck in the quagmire again?" asked Xiao Tao with a confused expression.

"Pretty much. ”

Xu Mang nodded and said indifferently: "But don't panic... I can always come up with a solution, but I'm curious about what kind of strange reaction the combination of epitaxial technology and stripping method will have. ”

“？？？”

“？？？”

A combination of the two technologies?

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

"Professor Xu. ”

"You're the only one in the world who thinks this way. Koyanagi smiled: "These two technologies are completely independent, how can they be combined, the epitaxial technology is a vapor phase epitaxy process, and the stripping method is a pure gift from nature, which is different." ”

"Really?"

"I'm a person who likes to break the mold the most. Xu Mang said seriously: "I think it can be done." ”

Facing the stubborn Xu Mang, the two just smiled helplessly, this time Xiao Tao and Xiao Liu didn't dare to talk nonsense, and they were completely slapped in the face by Professor Xu, isn't it embarrassing?

"Come!"

"Assign the work, Xiaotao, you use epitaxial technology to prepare perovskite material films, and Xiaoyanagi, you use stripping method to prepare perovskite material films. Xu Mang said solemnly: "You don't need to succeed, just get as close as possible, and then find the problem." ”

"Oh..."

"Okay. ”

After the two nodded, one of them asked curiously, "Professor Xu... What about you?"

"Me?"

"I'll supervise your work. Xu Mang glanced at him and said angrily: "My wife paid your salary." ”

“...”

“...”

For this reason,

There is no way to refute it at all!

One afternoon,

The progress is quite reliable, and almost all the experiments were completed in three hours, but according to the calculations, the success rate is not even half of it, especially the Koyanagi who uses the peeling method, which is directly one percent probability.

Xu Mang was not surprised by this, but Xiao Tao and Xiao Liu were a little frustrated and couldn't accept this fact.

The calculation knows that the critical point of thickness is atoms, but what is the use of this? Without relevant technical support, the light breaks through the theoretical framework, and in the end it still finds nothing.

At the end of work,

Xu Mang had just stepped forward, and the glasses girl Xiaotao found Xu Mang.

"Xu..."

"Professor Xu, I would like to apply for a transfer out of the laboratory. Xiao Tao said cautiously: "Professor Xu... It's not that I'm unwilling to take on this responsibility, it's just... There is no hope in sight. ”

“...”

"Let's not wait a few more days. Xu Mang said calmly: "Anyway, you are not bad for the past few days, what if there is any huge breakthrough?"

"Oh..."

Just finished speaking,

Xu Mang hadn't taken a few steps before Xiao Yanagi stopped him again, and he also applied for a transfer from the laboratory.

This time

Xu Mang agreed, and by the way, Xiaotao's application was also approved.

"Ugh..."

"Mortgages... actually forced the two of them to die so much. After Xu Mang knew why the two applied for transfer, he couldn't help but show a helpless expression.

...

night

Xu Mang carefully broke free from Xiao Man's bear hug, put on his clothes and pants and left the bedroom silently, and went to his study.

Turn on the lights,

Sitting in front of the computer, looking at the data of the two reports, I was a little confused for a while.

"The system... What is the exchange value of the preparation technology of atomic-scale perovskite material films?"

[After systematic identification, the exchange value of the preparation technology of atomic-scale perovskite material film: 1 (physical)]

[Systematically identified, the exchange value of the preparation technology of atomic-scale perovskite material films: 5000 (chemical)]

Belch?

Chemistry?

That's not right... Chemistry and reaching the mastery level, why do you still need 5,000 skill points?

Does this have anything to do with chemistry?

Xu Mang looked at the two research reports repeatedly, not to mention... I really found an application in chemistry.

Pay!

Xu Mang is too lazy to engage in chemistry again, mainly because it is too troublesome... It's a waste of two days to go back and forth, and it's not worth it to think about.

In a flash

After repeated research, it was found that only water-soluble Sr3Al2O6 was needed as the basis for the so-called perovskite material film through the reactive molecular beam epitaxy method.

And most importantly, the prepared films can also be transferred to different substrates, especially crystalline silicon wafers and porous carbon films.

"I see!"

"By dissolving the buffer layer in water, millimeter-sized monocrystalline perovskite oxide films are released from the substrate. Xu Mang sighed, and couldn't help but feel that this world is so wonderful.

meanwhile

United States,

Headquarters of the Physical Society.

Henry Mirren came to the place of work as usual, since he got the result formula of Xu Yang, the whole person has been a lot easier, but there is some confusion, many people have reported to him that the formula of Xu Yang's structure is too complicated and the calculation process is too much.

Faced with this problem,

Henry Mirren formed a group of simplified formulas, but twenty-four hours passed, the group's progress was zero, and there was no room to be simplified, and every number and symbol of it was particularly important.

Bang bang bang,

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

"Hello?"

"Miller?"

"Call me in the morning, is there anything wrong?" asked Henry Mirren with a smile.

"You seem to be in a good mood today?" A rough voice came out, "I want to ask about the research materials on perovskite material thin films, how is the progress of Huaguo's side?" Xu Mang must be very angry, right?"

Words fall,

It was a burst of laughter.

"I think..."

"Now Xu Mang should be so irritable that he can't even sleep well, and he has cheated so many people, and we have cheated him. Henry Mirren laughed and said, "In the words of their country, this is called good and evil rewarded." ”

however

The two of them didn't know that

A storm has begun to brew.
