Chapter 497 I Like the Feeling of Walking on the Edge of a Cliff

Xu Qingzhou took a stroll around the laboratory, checked the data and equipment operation, and did not stay long. He became a hands-off boss again and went to the library to do calculations.

Although Sun Simin and Mars are not yet able to get the hang of it, they can still help with chores and watch over the experiments. Carson can handle it alone.

It is hoped that through mathematical methods, statistics, modeling, fitting and other tools, discrete and superficial data can be transformed into a quantitative description of the laws of phenomena, and the laws and correlations between implicit parameters can be explored.

On the other side, after Professor Carlisle and Xu Qingzhou separated, they went straight to Professor Roberts' office.

"A glass of iced Americano, thank you."

Professor Carlisle said to Horn, then sat down in front of Professor Roberts and said helplessly: "Congratulations, you win."

"I'm happy to hear that," said Professor Roberts.

This young man has a terrible persistence at certain times. Perhaps it is this persistence that has earned him the honor he has today.

"Thank you." Professor Carlyle took the coffee handed over by Horn, took a sip, and said with a tone of great regret: "The Department of Mathematics finally has its own Fields Medal winner, but he went to do physics."

"At least, he went to class, didn't he?"

Professor Roberts shrugged.

Professor Carlisle said in a deep voice, "Perhaps I should learn from your optimistic attitude, but the fact is that universities like Princeton and Cambridge have already achieved phased results, while they are just getting started. No, I have to go back and study how to make this Fields Medal winner play his due role."

October 10, Friday, it rained last night. When I opened the window, humid air came in through the gaps.

Xu Qingzhou stood in front of the window holding a cup of coffee and took a long breath. After the rain, the sky was clear and blue. By the river, the maple red and caramel-colored sycamore leaves were layered, and the fallen leaves were all over the ground.

The process of making the optimized model was much more complicated than he had imagined, and it would take at least four or five days to complete.

This is also because with Song Yao watching over me, it’s not easy for me to stay up late.

Otherwise, like before, he was confident that he could produce it within two days.

But having learned the lesson from his previous life, he realized that the body is the capital of revolution, so he became much more restrained and would not endure any hardship if he could avoid it.

I don’t have a wife or children now, but I still have a wife, so I need to take better care of myself.

He stretched his stiff neck and said, "I will be able to complete Song's high-frequency signal synthesis work around the 25th. The model has not encountered any difficulties so far. Not bad, everything is on track."

At this moment, the phone on the desk vibrated.

"Professor, according to your request, we have conducted four more graphene substrate preparation experiments, but now there is unfortunate news. In the four experiments, graphene experienced a "carbon atom disco" at 350°C. Sorry, I think this description is very appropriate, sp→sp hybridization, causing the electron mobility to plummet by 40%. The final result is that the substrate structure is damaged. The data has been sent to your email."

"Professor, I think it is necessary to find a chemistry expert to analyze the composition problem for us."

Carson reported on the phone.

Well, everything was going smoothly just now, but now something went wrong.

"Don't worry, let me take a look at the data first."

Xu Qingzhou secretly thought that it was a crow's mouth. He sat down and opened the data report in the mailbox. He quickly found the anomaly in the data.

XPS test results show that the SnO impurity content is 8.7%.

Deposition rate 0.2 nm/s
There are problems with all of them.

This means that the precursor was chosen incorrectly?
Xu Qingzhou frowned, recalling the materials he had read and the physics experiments he had done, to see if he had encountered the same difficulties.

It should be physically possible.
How about considering chemistry?

He then drew a structural diagram of Sn(NEt) to see where the error occurred.

Traditional Sn precursors have poor thermal stability. By using diethyltinamine (Sn(NEt)) instead, the decomposition temperature of the precursor is reduced to 350–400°C, which should significantly reduce Sn volatilization.

But now the result is just the opposite.

On the other end of the phone, Carson saw that Xu Qingzhou hadn't spoken for a long time, so he couldn't help but shout, "Professor?"

"Give me 2 minutes."

Xu Qingzhou came back to his senses and pulled out another manuscript from the side.

"okay."

The sound of rustling writing could be heard in the living room.

Half of the manuscript was already filled with complex reaction equations. After a moment, Xu Qingzhou's pen suddenly stopped and he stared at the reaction he had sketched.

【SnO + 4H → Sn + 2HO】

That is to say, some Sn atoms will be oxidized into SnO (tin dioxide).

Found the problem!
Xu Qingzhou stared at the formula on the manuscript, his brows relaxed, and said, "Go borrow a PlasmaPro 100, add H plasma, and reduce SnO to metallic Sn in real time. When the film grows, use hydrogen atoms to solve the oxide."

"what?"

"you will not?"

Xu Qingzhou frowned and asked, it’s just adding H plasma, the operation is not difficult.

"No, no, no, it's a very simple operation, professor. Did you come up with it on the spot?"

"has a problem?"

"no problem."

Xu Qingzhou nodded slightly and ordered in a deep voice: "Okay, do four more groups and produce the data of the new precursor first. I need to see the results before Friday. Is that ok?"

"no problem."

Xu Qingzhou hung up the phone and immersed himself in calculations again.

In the laboratory, after Carson hung up the phone, Mars asked curiously, "What did the professor say?"

Sun Simin's attention also shifted away from the textbook in front of her.

"Let's add H plasma and do four more control tests under the current conditions," Carson said in a deep voice.

Mars was surprised: "The professor is also proficient in chemistry?"

"Shouldn't we have adapted to it long ago?"

Carson said with a shrug.

Mars was stunned, and felt that what Carson said seemed to be correct. The longer he met him, the more he felt that the professor was unfathomable. He was a math expert, not weak in physics, and knew a little bit about maintenance.
Now it seems that I have some understanding of chemistry.

"I have to go to the equipment management office."

Carson did not waste any time and prepared to start working immediately. There were only four of them in the research group, and the boss could not come, so the important task fell on him.

Although he is very busy, he is full of energy.

Quite exciting.

I like the feeling of walking on the cliff of failure and success.

If the experiment fails, everything will be lost.

The experiment was successful and created a miracle.

apartment.

Xu Qingzhou was not affected by the laboratory and was busy with his own calculations. Now he had to at least make a sample that could be viewed before further iteration to see if some of the previous concepts could be applied to superconducting films.

Take making a car for example. No matter how good the technology is, you must first produce a car that can drive normally.

【Objective function: [\begin{caN_{ext{Sn}}\quad (ext{SnO}_2 ext{content})\end{cases}]】

[Phase field model.

F =∫[ f(φ)+(ε/2)|φ|2}{2}|\nabla \phi|^2 \right] dV ]】

He has combined kinetic equations and free energy functionals to simulate grain growth and competition mechanisms during annealing.

The Monte Carlo simulation has also been mostly completed, which is sufficient to determine the quantitative relationship between doping density and grain size.

The next step is the most troublesome one.

Use topology optimization to reduce surface roughness and improve mechanical properties.
