What just happened?

Is this manuscript a manuscript that breaks through the limit theory?

The two of them looked at Xu Mang with horror on their faces, fear in their eyes, disbelief on their faces, and a little bit of confusion.

The ultimate theory that has troubled two-dimensional material researchers all over the world for so many years... ended up being solved by Professor Xu in one night? How is this possible... So many people around the world have spent so many years, but it is not as good as Professor Xu

One night?

"Xu..."

"Professor Xu?"

"These... these pieces of white paper are the legendary manuscripts that break through the limit theory?" The glasses girl Xiao Tao looked at Xu Mang in surprise, pointed to the manuscript on the table, and asked: "Are... are you sure?

Is this a manuscript for breaking the limit theory?"

Xu Mang took out a pack of 'idiot melon seeds' that he had not finished eating yesterday from his handbag, nodded with a smile on his face, and said: "Yes... this is the manuscript that breaks free of the limit theory. Take a look at it for yourselves, yes.

Okay...make me a pot of tea after watching this."

"..."

"..."

Neither of them spoke. Xiao Liu silently opened the manuscript that Xu Mang had thrown over, but just took a glance at it. In an instant...she fell into dementia, and the shock on her face at the beginning turned into a bit of panic.

Atomic level?

This simply subverts the three views!

"well?"

"What's your expression?" Xiao Tao looked at his colleague with a confused face and found that his expression changed a little. He was still a little surprised before, but at this moment he looked a little nervous and scared.

"You... read it yourself." Xiao Liu handed the manuscript to Xiao Tao.

After receiving the manuscript, Xiao Tao also opened it and took a look. For a while, he fell into the same situation as Xiao Liu, and felt a great sense of fear about the content of this manuscript.

The two of them looked at Xu Mang. They looked at Xu Mang, who was cracking melon seeds and playing with his mobile phone. His face showed secret expressions of joy from time to time. In one night... just one night, he cracked the material.

Limit theory in history.

he...

How on earth did he do it?

"Professor Xu!"

"Stop knocking melon seeds... tell us how you got rid of the limit theory?" Xiao Tao asked with a surprised look on his face: "Professor Xu, stop knocking... really, stop knocking, please hurry up and talk to us

Tell me, how did you discover that the limit is at the atomic level?"

"I wrote it above."

"Don't you see it at all?" Xu Mang asked curiously while cracking melon seeds.

"..."

"..."

Saw it,

Don’t understand!

Suddenly the two of them lowered their heads in embarrassment. The content inside was completely beyond the scope of their understanding. It relies on pure theory and mathematics to explain a phenomenon in the microscopic world. I'm sorry... I really can't see it.

Understand.

"Well..."

"Professor Xu, we...we didn't understand." Xiao Tao said embarrassedly: "We are studying materials, and you are completely starting from the perspective of mathematics and physics. Although we are not bad at physics, we are not bad at it.

...Faced with this level, there is really nothing we can do.”

"oh..."

"Forget it, you probably won't understand what I said." Xu Mang licked the melon seeds with a nonchalant expression, raised his head and looked at Xiao Tao, and said seriously: "Go and make me a pot of tea. Let's start in the afternoon.

Research preparation technology.”

"yes!"

...

afternoon,

Xu Mang, Xiao Tao, and Xiao Liu started intense research work and had the theory to break through the limits. The rest was to study the preparation technology according to the theory. There are two preparation methods in the world, one is the peeling method...

This method once won the Nobel Prize in Physics. It can be done with simple tape, and the object is graphene.

The other is the epitaxial method. There are certain requirements for growing a layer on a single crystal substrate, and the single crystal layer has the same crystal orientation as the substrate, as if the original crystal has extended outward for a period.

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 crystal lattice of the two-dimensional material will collapse, but in the current technology, there is no such technology.

atom?

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

However, this idea was dismissed by himself. Using a scanning tunneling microscope would be a complete waste of limited resources. If you want to make 10,000 independent perovskite films, it is almost impossible.

what to do?

It’s so damn finished again!

"Professor Xu?"

"Are we stuck in the quagmire again?" Xiao Tao asked with a confused look on his face.

"Almost."

Xu Mang nodded and said calmly: "But don't panic... we can always come up with a solution, but now I am particularly curious about what kind of strange reaction there will be when the epitaxial technology and the peeling method are combined."

"???"

"???"

Combination of 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." Xiaoliu said with a smile: "These two technologies are completely independent, how can they be combined together? Epitaxy technology is a vapor phase epitaxy process, while the lift-off method is a pure gift from nature.

Same."

"Yeah?"

"I like breaking rules 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. Wouldn't it be embarrassing to be completely slapped in the face by Professor Xu again?

"Come!"

"Distribute the work. Xiaotao, you use epitaxial technology to prepare perovskite material films, and Xiaoliu, you use the exfoliation method to prepare perovskite material films." Xu Mang said seriously: "You don't need to succeed, as long as you are as close as possible,

Then just find the problem.”

"oh..."

"OK."

After the two nodded, Xiao Tao asked curiously: "Professor Xu... what about you?"

"I?"

"I supervise your work." Xu Mang rolled his eyes and said angrily: "My wife pays your wages."

"..."

"..."

For this reason,

There is no way to refute it!

one afternoon,

The progress was pretty reliable, and almost all the experiments were completed in three hours. However, calculations showed that the success rate was not even half a percent. Especially for Xiaoyanagi who used the peeling method, the probability was directly one percent.

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

Calculations have shown that the critical point of thickness is atoms, but what is the use of this? Without relevant technical support, light has broken through the theoretical framework, but in the end, nothing has been achieved.

When getting off work,

Just as Xu Mang took the first step, the glasses girl Xiaotao found Xu Mang.

"Xu..."

"Professor Xu, I would like to apply for transfer out of the laboratory." Xiao Tao said cautiously: "Professor Xu... It's not that I don't want to take on this responsibility, it's just that... I don't see any hope at all."
To be continued...
