I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 521 Three Plans Far Ahead

In the morning, the quiet city gradually became noisy, with vehicles flowing on the road and office workers hurrying on both sides of the road. It seemed to be no different from the situation in China.

Song Yao and Xu Qingzhou chatted for 10 minutes. Seeing that it was already 8:, she didn't want to waste any more time. "Professor Xu, I have to go out now."

"Ah."

"I stayed up late last night and got up at 7am. Remember to take a good rest at noon. You won't die if you miss two hours of calculation. You are so young but you are overdrawing yourself. You have two big dark circles under your eyes."

Student Song kept muttering to himself.

"Okay, I'll do whatever you say."

Xu Qingzhou responded with a smile. She was obviously a quiet and cold girl, but she had to be nagged all day long.

However, the mumbling school beauty Song is particularly cute.

Seeing that Xu Qingzhou agreed, Song Yao finally grabbed Xu Qingzhou's head twice, then ran to change her shoes.

Xu Qingzhou stood up and helped School Beauty Song fix her scarf and zipper her clothes.

School beauty Song stood there obediently, letting Xu Qingzhou work on her body, looking at him with her round eyes.

It is said that the eyes are the windows to the soul. This girl's eyes are really beautiful, deep, and crystal clear. Especially at this moment, Xu Qingzhou felt itchy in his heart.

"Look at that."

Xu Qingzhou pinched the school beauty Song's cheek. Song Yao slapped his hand away, but reached out her own.

"Don't move." Before leaving, Song Yao turned Xu Qingzhou's face over and kissed him hard, leaving a lipstick mark, before leaving with satisfaction.

"Just torture me."

Xu Qingzhou complained that School Beauty Song seemed to like leaving lipstick prints on his face, like stamping a stamp.

Song Yao glanced at him arrogantly, and after walking a few steps, she stopped and said, "Next time you stay up late secretly, you'll be dead."

After threatening Xu Qingzhou with her fist, School Beauty Song walked out with brisk steps.

"Bah, you're still yelling about being gentle all day long." Xu Qingzhou shook his head, closed the door, turned around and went back to deal with the manuscript on the table. On the way, he picked up Er Miao who was drowsy on the sofa.

I can only say that it’s different when there’s a woman at home.

For my past self, staying up until three o'clock was just a piece of cake. It was common for me to design experiments all night long. Even when I later became the person in charge of a key project, I often only slept for three or four hours.

The result is needless to say.
Anyway, I can't follow in his footsteps. Who knows if I can be reborn if I die suddenly again? The most important thing is that I am married now, and I have a sweet and soft school belle, Song.

"Meow~"

In his arms, Ermao struggled, protesting against the two-legged beast for disturbing his sweet dream, but he seemed to realize that he could not escape the clutches of the big villain, so he simply fell asleep snoring in Xu Qingzhou's arms.

At this time, two days had passed since the Song Yao model was completed.

It's no wonder that after letting his brain relax, Xu Qingzhou really came up with some good ideas. After a small start, inspiration came pouring out like water from a floodgate.

So far, he has come up with three plans.

First, combining quantum mechanics, which he is best at, with reference to the wave-particle duality of light, he prepared sub-nanometer YO quantum dots through quantum confinement effect, and used its quantum size effect to increase the depth of the pinned potential well.

The specific implementation path needs to be further discussed. The second method is to refer to the Schrödinger equation and wave mechanics model, and epitaxially grow topological insulators, such as BiSe, on the surface of NbSn film, and use its topologically protected surface states to suppress the movement of magnetic flux lines.

Then there is the last resort.

Xu Qingzhou, who had participated in the lunar exploration project, felt that he could refer to the design concept of stability in extreme environments and pre-implant He ion irradiation-induced nanocavities in electronic equipment. The cavities could capture irradiation defects and dynamically repair the lattice. In other words, ion implantation technology could be used to generate a controllable cavity array, and molecular dynamics simulation could be used to verify the efficiency of the cavity in capturing defects.

"Well, now it's time to choose one."

In fact, all three experiments are technically difficult, and time is limited, so we can only carry out one of them first, break through the current bottleneck, and then consider the subsequent small problems.

Xu Qingzhou gently turned the pen in his hand, his mind working rapidly, comparing the pros and cons and feasibility of the three options.

A long while passed.

Xu Qingzhou's eyes fell on the second option.

【Topological superconducting interface engineering. 】

The difficulty is relatively low. It only requires adding angle-resolved photoelectron spectroscopy (ARPES) to the existing equipment to verify the coupling between the topological state and the superconducting state, and then combining Monte Carlo simulation to optimize the interface electron transmission path.

He had previously performed relevant calculations and discovered that when doing topological design, BiSe would produce a mismatch with the NbSn lattice, resulting in interface defects. This can be combined with the transition layer studied by Carson and his team, and through the transition layer, the mismatch can be reduced by 2%.

Once completed, the current performance can be improved by at least 50%, reaching commercial level.

If all three solutions are completed
He was far ahead of the others.

This is the power of a cheater. While his peers are still on the 40th floor, he has already reached the 99th floor.

Unfortunately, this will be a huge project. Unless he stays here for a few more years and builds a more complete team, it will be too difficult.

"Whoo~"

Xu Qingzhou let out a long breath, woke up Er Miao and put him on the floor, then picked up a pen and started calculating.

The model and calculation of YO nano-doping have been completed long ago. Now we need to solve the problem of topological superconducting interface engineering and YO nano-doping synergistically optimizing NbSn thin films.

Add BdG equation modeling and coupling strength quantification, independently model the coupling between topological states and superconductors, quantify interface parameters, and finally modify the pinning force model he had done. Superimpose the topological interface contribution and the YO contribution ( F_{ext{YO}}).

Funds are limited, so the cost of trial and error must be significantly reduced. The best way, of course, is to first conduct mathematical simulations to ensure that the synergistic effect of the topological superconducting interface and YO nano-doping technology is maximized.

As before, through experimentation and iteration, we finally ensure the prediction accuracy and lock in the optimal process parameters.

After writing for half an hour, Xu Qingzhou took out his mobile phone again and sent Carson the equipment that needed to be added, asking him to apply for it as soon as possible and find someone to install it.

When it comes to labor, foreign countries' efficiency has always been impressive.

The equipment must be prepared in advance so that the plan can be produced and the experiment can be started immediately.

For the time being, we need a molecular beam epitaxy machine equipped with Bi, Se, and Nb sources, Riber 32P. And a focused ion beam machine of FEI Helios 600i.

After writing out the framework of the experimental plan, he did not continue. When it was noon, he felt dizzy from staying up late.

Xu Qingzhou didn't find it troublesome, so he simply cooked a bowl of noodles, covered it with the leftovers, ate it, and went straight back to his bedroom to sleep.

Before going to bed, he took a photo and reported his situation to Song Yao.
