Chapter 523: I'm Actually Quite Good at Physics

"Topological superconducting interface engineering?"

"Jc ≥ 2.0×10^6 A/cm²?"

Carson stared at the email Xu Qingzhou sent, checking more detailed information.

"Looking at your expressions, I suppose you have something to say?" Xu Qingzhou paused, waiting for team members to ask questions.

Ma Ersi smiled sheepishly and said: "Professor, I have a small question. Okay, not a small question. Forgive me for speaking bluntly, but aren't we taking too big a step?"

Their best superconducting thin film sample performance currently was only Jc ≥ 1×10^6 A/cm².

This was a direct doubling.

Xu Qingzhou smiled and said: "Mr. Ma Ersi, I'm very happy you can be so humble, but not this time. I believe this is within our capabilities."

"Epitaxially growing topological insulators on the surface of NbSn thin films... utilizing their topologically protected surface states to suppress magnetic flux line motion..."

Carson was puzzled: "Professor, is this method of yours... useful? Just mentioning one point, although I don't know much about topology, I can still see that topological insulator surfaces are easily oxidized. For example, BiSe forms BiO after exposure to air, destroying the topological surface state. How should this be solved?"

"Theoretically, it can be solved. We can use a single layer of graphene or h-BN to cover the surface of the topological material. Don't have that expression; science lies in exploration, and that's what we're doing."

"."

"Hey, shall we make a bet? Let's bet on this experiment. The loser treats everyone to drinks."

Carson snapped his fingers and said excitedly.

Sun Simin shook her head like a rattle, while Ma Ersi was somewhat tempted.

"Hold on first. Regarding betting, I suggest you do it privately. Of course, although I won't participate, I suggest you bet on the successful side. Alright, back to the main topic, let's talk about the experiment."

Xu Qingzhou pulled the off-track meeting topic back.

Right now, all the major laboratories are advancing at the same pace; if a small, amateur team like theirs doesn't have some black technology, wouldn't they just be running alongside them as mere decoration?

"We need to complete sapphire substrate pretreatment and BiSe topological layer growth on the basis of the original experiment..."

Xu Qingzhou explained the steps that needed to be added to the experiment: sapphire substrate polishing, constructing topological materials... He didn't forget the gradient transition layer that Carson and the others worked overtime to create.

Time passed second by second.

Sun Simin and Ma Ersi were basically listening, while Carson interrupted from time to time, raising the doubts in his heart.

A whole morning passed just like that.

"You all understand now, right?" Xu Qingzhou had already gone through the entire experimental process and details.

"Understood."

Carson nodded. Unlike before, after deeply understanding the scheme, he found it indeed had strong feasibility.

If nothing went wrong, they could really give their peers a heavy blow.

You know, when he posted on Twitter, there were quite a few people in the comment section making cold remarks.

He looked at the experimental scheme on the screen and still couldn't help but marvel: "Professor, if I remember correctly, you majored in mathematics during your master's and graduate stages, and only took physics during your undergraduate years..."

Combining the experiment with the Schrödinger equation and wave mechanics model to create a topological superconducting interface—this was the first time he had seen such a wild and imaginative idea.

Plus the quantum dot precision doping and self-healing nano-cavities the professor mentioned...

"I don't know if I've mentioned it, but let's count it as a secret."

Xu Qingzhou stood up, put on his white lab coat, turned to look at the few people gazing at him, and smiled faintly: "I'm actually quite good at physics."

Not only good, but in the field of quantum mechanics, one could say he was terrifyingly strong.

"."

"Okay, let's start."

Xu Qingzhou took the lead and walked into the laboratory.

"Alright, I can't refute that."

Carson shrugged.

Ma Ersi was stunned, gazing at Xu Qingzhou's back, and sighed: "When will I be able to be like the professor, speaking with such level?"

And Carson and the other two didn't waste time, marching into the laboratory.

First, sapphire substrate pretreatment: ultrasonic cleaning, oxygen plasma treatment, in-situ annealing...

The second part was operated by Carson; they had already produced a good WS transition layer growth these past few days.

Fortunately, everything went without any accidents, advancing in the expected direction.

January 30th, 11:00 PM.

"I'm back."

Xu Qingzhou dragged his exhausted body back to the apartment, hung up his down jacket, and changed his shoes.

Song Yao was wearing white pajamas, sitting cross-legged on the sofa, holding Er Miao, watching "Friends." Seeing Xu Qingzhou enter, she scooted over to leave him a spot.

"Finished?"

"Mm."

Xu Qingzhou nodded slightly, collapsing on the sofa, "Just stuffed the sample into the superconducting performance testing system, but it will take at least until tomorrow night to see the results."

The team worked overtime for 3 days, day and night, finally making 4 superconducting thin films.

But superconducting testing relied on a shared platform. Only today did they barely finish the Transmission Electron Microscope (TEM) and Atomic Force Microscope (AFM), and superconducting performance testing took 24 hours.

Song Yao put Er Miao down, groped her way into Xu Qingzhou's arms, and pressed her face against his sweater.

Pressed tightly like this, she could feel the strong heartbeat and the scorching temperature coming through the sweater.

Additionally, there was the scent unique to Xu Qingzhou.

It was very comfortable for the two to be pressed together; even, she always had the urge to peel off Xu Qingzhou's clothes.

Song Yao sniffed subconsciously.

However, noticing her small action, she couldn't help but smile, thinking: "The way I am, it's like I'm really absorbing Xu Qingzhou's Yang energy."

Without knowing it, she had become so strange.

She wouldn't be like this before.

"You're crushing me."

Xu Qingzhou pushed away the girl who was pressing her whole body on him with disdain.

Song Yao glared with her eyes in anger, dissatisfied that this guy disturbed her thoughts, and collapsed back down with a sullen face.

Xu Qingzhou smiled helplessly.

Not to mention, although there was a suspicion of pretending before, some small temper tantrums now were truly cute.

The two lay like this for a few minutes.

Song Yao raised her head, climbed up from Xu Qingzhou, "You stink, go take a shower quickly."

Xu Qingzhou: "?"

No, when did you learn the art of left-right mutual fighting?

Just now you insisted on lying down, now you're starting to despise me.

He didn't move, adjusted to a comfortable position, and continued lying down, saying lazily: "Rest for a while before going."

Song Yao stared at Xu Qingzhou and released her trump card: "Professor Xu, are you not capable anymore?"

"."

Xu Qingzhou went to the bathroom with a dark face. Before stepping into the door, he threatened fiercely: "Little Song, you wait."

Song Yao stared at the TV, hummed without turning her head, knowing this trick worked. She thought, shuffling in her slippers to close the curtains.

Xu Qingzhou came out wiping his hair, and the school beauty was already waiting considerately with a hairdryer.

10 minutes later.

Xu Qingzhou took the hairdryer from Song Yao's hand, stood up, and stuffed it into the cabinet of the vanity. Just as he put it away and turned around, he noticed the school beauty had already appeared behind him at some point, her hair already tied up with a rubber band.

He looked at the approaching school beauty and gave up resistance, "Be gentle."

The tides turn; sooner or later, there would be his home court.
