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

Chapter 486 Do you want to watch a movie with simple scenes together?

In the laboratory, Xu Qingzhou did not participate in the chat of Carson and others, and focused his attention on the parameter panel.

For CVD growth, the temperature was raised to 1°C in a H/Ar (flow ratio 10:1050) atmosphere, and CH (10 sccm) was introduced for growth, followed by a 4-hour wait.

After completing the first step, Xu Qingzhou stayed in the laboratory while Carson and the other two went to eat. Soon, the only sound left in the laboratory was the low muffled sound of the equipment running.

After carefully checking the equipment operation, he turned to the office next door, turned on the computer and checked the CVD growth.

Seeing that there was nothing wrong with the data, he took out the information on the preparation of NbSn thin films from his bag.

Two major problems will be encountered during the experiment: interface stress and composition control difficulties, which to a certain extent determine the performance that the film can achieve.

For the former, Xu Qingzhou used a method he had used before, low-temperature ALD and gradient annealing, to find a way to reduce the coefficient of thermal expansion.

Although it was used in the design of silicon-based quantum dots at the time, the essence remains the same, so let's give it a try.

The problem of ingredient control is relatively troublesome.

A lot of adjustments need to be made, such as precursor optimization, sample replacement, or plasma parameter optimization, etc. At present, we can only make preparations, and everything can only be adjusted after the first round of experimental data comes out.

At 3 pm, Xu Qingzhou and Carson entered the laboratory again.

After cooling to 300°C, a PMMA protective layer was spin-coated.

Finally, the copper foil was electrochemically stripped and graphene was removed to SiO/Si substrate, and PMMA was removed by acetone.

This step takes about 2 hours.

Leaving Carson to check the equipment, Xu Qingzhou returned to the office to check the progress of other research groups.

Research teams doing cutting-edge experiments will pay attention to the dynamics of their competitors like "detectives", which can accelerate scientific breakthroughs to a certain extent. After all, there is pressure only when there is competition.

Of course, one's spiritual faith may also collapse.

For example, once in Princeton, Xu Qingzhou was running data in the laboratory one day when he suddenly heard a burst of shouting in the corridor.

When I walked out, I saw an old man crying miserably.

Later I learned that this guy was preparing to work on two innovative ideas. After working on them for several months, the first innovative idea was published in Nature by another research group.

My brother immediately changed to the second innovative point, but after about a month of work, he found out that it was published in Science again.

As a result, after two shocks, he could no longer hold on.

Of course, when doing scientific research, even if there is a minor error, you can still publish it after a slight revision.

However, Xu Qingzhou and his team don't have this problem.

Princeton University studies two-dimensional superconducting films, specifically topological superconductors and Majorana zero-energy modes. The goal is to reduce the interface defect density by 90% in order to promote the development of fault-tolerant quantum computing.

Japan is focusing on niobium nitride (NbN) thin films, hoping to enhance their resistance to magnetic field interference and extend the coherence time to more than 400 microseconds.

Xia Guo is currently studying high-temperature superconducting films, hoping to design quantum chips that do not require ultra-low temperature equipment.

In terms of superconducting thin films, a new round of competition has just begun, and no one seems to have made any key progress at present.

4 pm.

Sun Simin and Mars came in after class.

Xu Qingzhou handed them two manuscripts: "Here is a list of books. I hope you can finish reading them within a month."

The experiment of preparing substrate-free NbSn thin films based on ALD and graphene substrate involves theories and methods from multiple mathematical fields.

Ordinary differential equations and partial differential equations are needed to describe the reaction of samples during the experiment, predict the growth rate of thin films, as well as linear algebra, regression analysis in statistics, etc.

Since you have joined the experiment, you can't just do odd jobs or be a mascot.

"Ah, Professor, are you sure you're not kidding, three books in one month?"

Mars grimaced.

"Of course. I will set the questions in a month. If you fail, I don't mind saving some salary money. You know, our research group's funds are tight, and we don't need people who can only wipe tables." Xu Qingzhou said with a smile.

He decided to put some pressure on them. These two were very talented and they would have no problem competing against each other.

Mars was in a bad state.

Sun Simin, on the contrary, took a deep breath and was full of energy: "Professor, I will definitely not let you down!"

"I ah, well, it looks like this month is going to be painful."

Mars looked at the three thick books, and then at Sun Simin who was standing beside him with great enthusiasm. It seemed that he would have to create a miracle to master the knowledge points of the three books in one month.

Xu Qingzhou shrugged and said, "OK, instead of being in a daze, I suggest you start right away."

At 5 o'clock in the afternoon, after handing the laboratory to Carson, Xu Qingzhou drove to buy groceries and then went home to cook. Because School Beauty Song was having her period, he had to work as a nanny for a while.

When the sun was hanging in the west, the two had finished their meal. Xu Qingzhou washed the dishes and came out to squeeze together with Song Yao.

Song Yao was completely wrapped in Xu Qingzhou's arms, checking messages on her mobile phone, responding to the concern from her little sister on the other side of the ocean.

After replying the message, she put her face on Xu Qingzhou's chest and closed her eyes.

She found that after being with Xu Qingzhou, she seemed to become more and more "weak". When she was tired from work, she liked to lie on him and complain. She would act like a spoiled child and ask him to get things for her if she could get them herself.

Song Yao rubbed Xu Qingzhou's body for a few times, and found a more comfortable position to hug each other.

Think about when I was in high school, I had to move tables for exams. I could easily lift dozens of kilograms of things, and I did it myself every time.

Addicted to male beauty.

How could I have imagined before that I would cry in a boy’s arms.

Xu Qingzhou hugged the girl and leaned on the sofa to rest. After a busy day, he felt completely relaxed when hugging the school beauty Song.

After a while, he whispered, "Don't move."

School beauty Song stuck to him and always liked to rub against him.

Song Yao's body stiffened, and she also noticed Xu Qingzhou's change. She pursed her lips and got up from Xu Qingzhou, "Let's watch a movie."

Bah, pervert.

She flipped through the remote control for a long time and gave the choice to Xu Qingzhou: "Do you want to watch a movie?"

"I thought of one?"

"what?"

"It's a very classic. I used to watch it often. What's the name? It's that movie with a few actors and simple scenes."

Xu Qingzhou said, touching his chin.

bang~
Xu Qingzhou was hit on the head.

"Is your forehead made of iron?" Xu Qingzhou complained, grinning and rubbing his chest.

"Come to death!"

Song Yao stared and said unhappily, "Xu Qingzhou, are these the only messy things in your mind all day long?"

"What was I thinking? You didn't think I was talking about some educational film."

"Is not it?"

"I'm talking about 'The Man From Earth'."

Xu Qingzhou pinched the school girl Song's face and said faintly, "Xiao Song, you are thinking the wrong way. Of course, if you really want to see it, I can also watch it with you."

Xu Qingzhou felt that there was great potential for him, and he hadn’t even watched a porn movie with School Beauty Song yet.

Well, that's quite interesting.
