NTU, in a research room in the Physical Materials Research Building.
Chen Zhengping is busy with his students. In recent years, his research topics are shifting from condensed matter physics and high energy physics to the structure and physical properties of low-dimensional materials, as well as spin electronic materials.
This time, the preparation technology of low-dimensional material tungsten diselenide material was a new topic he started last year.
However, the material aspect is actually a bit like studying mathematical conjectures, either relying on time to accumulate experimental material data, or relying on inspiration and luck.
However, in the current material world, there are very few results achieved by luck. Most of the materials results rely on continuous experiments and the elimination of errors one by one, and finally some results can be developed.
This is the same all over the world.
Therefore, countries that started early in the field of materials will have a great advantage. Because of time, these countries have accumulated enough data.
"Tutor, the experimental results are out, but they are not ideal."
"We still can't find a way to make tungsten diselenide form a nanoscale single-layer structure on a silicon oxide silicon wafer or an optical sapphire wafer. The special crystalline state formed during the bonding process is too difficult to calculate, or
It’s impossible to calculate at all.”
"Then please come to the Materials Research Building. I have some mathematical problems on my project and I need a mathematician to help."
Yes, why did he forget about Xu Chuan? If he can prove a world-class conjecture, his mathematical skills have surpassed more than 90% of mathematicians. Maybe he can do it.
"Hello, mentor."
"What's wrong, tutor? I'm in the dormitory. What's wrong?"
"At least currently we don't have accurate data to indicate how we can constrain it. It's really difficult. Maybe we should seek help from the School of Mathematics and see if they can arrange for two professors or doctoral students in this area.
Come and help me."
In addition, there was a junior fellow student who had a problem with his accent and habitually pronounced "brother" as "bear", so the junior fellow apprentices behind them all called him "Master Xiong".
"Okay, then I'll wait for you here."
When Chen Zhengping was thinking about who would be better to ask for help, Fan Pengyue's voice rang out again, making his eyes light up.
After looking through the information in his hand, Chen Zhengping also had a headache. Judging from the information, the situation was just as his current disciple Fan Pengyue said. They could not find a way to smoothly convert tungsten diselenide into a monomer.
The crystal lattice of the molecular layer spreads out.
Although he used to work as a laborer, this was a good opportunity for him to get in touch with materials science in advance.
"I'll go down and pick up my junior brother right now."
"Where's the experimental data? Show it to me first."
The current project of ‘vapor deposition of tungsten diselenide on silicon oxide silicon wafers or optical sapphire wafers to construct single-atom layered nanostructured materials’ is also his PhD graduation project.
"Well, don't worry, do you know where the materials research building is? Forget it, just wait in the dormitory and I'll ask Fan Peng to go over and pick you up."
This is his nickname because he is tall, tall, strong, and has thick, thick hair. He does not look like an academic, but looks like a black bear.
"You kid are also joining in the fun. The instructor told you something. I'll take you up."
After hanging up the phone, Chen Zhengping looked at Fan Pengyue. Before he could speak, Fan Pengyue stood up.
"Oh, okay, I'll be there right away."
Soon, Xu Chuan arrived at the Materials Research Building and saw 'Master Bear' Fan Pengyue waiting here.
According to the development trajectory of his previous life, he will have to wait until this time next year to have initial contact with materials science.
Various methods have been tried, but none have been successful.
After all, mathematical calculations are not his strong point, but who should he hire?
Professor Zhou Hai? Or Professor Lin Xingan?
"No need to bother senior brother. I know the location. Just ask him to pick me up downstairs in the Materials Research Building. I'll be here right away."
He is currently Chen Zhengping's largest disciple and has been following him for more than four years. It can be said that he has been following his mentor since he turned his research goal to materials.
"I said there is material data that needs to be processed, but what material are you studying?"
Chen Zhengping stood up and took a stack of printed information from Fan Pengyue's hand. On it were various undulating images, point-line separation structural drawings, and various labeled data.
As time passed, the butterfly effect brought about by his rebirth became more and more obvious. Just like today, his mentor asked him for help, something that had never happened in his previous life.
After receiving the call from his instructor, Xu Chuan immediately stood up, washed his face and rushed to the materials research building.
This is the biggest problem. To a certain extent, his eldest disciple is right. Maybe he should find a helper from mathematics.
"Well, I'll give him a call and see what he's doing now." Chen Zhengping responded and took out his cell phone.
But now they are stuck, and they have been stuck for more than a month or two. They have been stuck for half a year on how to pave tungsten diselenide.
It's now almost a full year ahead of schedule.
"By the way, mentor, didn't you recruit a very powerful new disciple this year? He proved a world-class mathematical conjecture. How about asking your junior brother for help first?"
Xu Chuan shouted in a long tone with a smile, and received a roll of eyes from Fan Pengyue.
In the laboratory, Fan Pengyue straightened up, rubbed his sour eyes and said.
The call was connected, and Xu Chuan's voice came over from the other end. Chen Zhengping asked: "Hey, Xu Chuan, where are you now? Is it convenient?"
"Master~Bear~"
Xu Chuan asked curiously. He was really not very clear about the research direction of his mentor Chen Zhengping for 15 years.
After all, it was more than a year later when he came into contact with the material, and the things he studied at that time should be different from now.
"You know the teacher's turn. Recently we have been studying a low-dimensional material, tungsten diselenide. It has reached the final stage, but the material data processing is stuck. We need a 'big~ mathematician' to come."
help."
Fan Pengyue said with a smile, emphasizing on the great mathematician and raising his voice a little higher, which was a response to Xu Chuan calling him "Master Xiong" before.
