Chapter 541: No matter how they struggle, they will be blown up

In late March, Xu Qingzhou put all his energy into the mathematical model of the stress compensation interface. This thing involves too many things, and even if he can use the school's supercomputer, it is still quite difficult to calculate.

Especially in the case of not being able to burn money to collect data through massive experiments, he can only strive for perfection, simulate experimental results through mathematical means, and infer the best variables.

Carson's side led two interns to iterate.

This day, he had just gone to the characterization testing center to get the report and met his former boss, Professor Vasquez, at the intersection. "Professor Vasquez, good morning."

"Good morning, Mr. Carson."

Carson giggled: "Congratulations, Professor, I heard your experiment is about to enter the third stage."

"If you hadn't sneaked away, you could have entered the third stage last month."

Professor Vasquez still had resentment about Carson pigeonholing him.

"You know, I can't stay idle."

Carson felt a bit guilty, just happened to walk to the intersection where they parted, and hurriedly ran away: "Hey, Professor, goodbye, I have to get busy."

"Get lost."

Professor Vasquez waved his hand, paused, and added another sentence: "By the way, if your lab is short of equipment, just come and get it."

"Thank you, Professor!"

Professor Vasquez nodded slightly, looking at the back of the student he had high hopes for, his expression complex.

Although he didn't want to admit it, he had to say that this guy made a correct choice; Xu Qingzhou's research group is now a hot project.

The outside world generally predicts that the patents in Xu Qingzhou's hands can bring them at least 300 million US dollars in revenue.

Half a year ago, he was still jumping with anger, sighing that his student was playing with his future.

Now...

Sigh~

However, if you want to say who is the most depressed, it shouldn't be him, it should be those guys in the project office and the board of directors, who had eyes but didn't see, missing a project that could make a lot of money.

At this time, the project office is holding a meeting.

On one side of the large square table, a fat middle-aged man in a suit said: "Hey, Mr. Wilson, are there any terms in our contract with Xu Qingzhou that can be 'discussed'?"

According to gossip, General Electric has already made contact with Xu Qingzhou and reached a certain cooperation agreement.

Calculating by 300 million, 30% is 90 million.

Even for a top university like MIT, this is also a huge sum of money.

"I asked Attorney Adams of the Technology Transfer Office, the signed contract is very perfect, there are no terms that can be utilized at all... That technology transfer agreement is an impregnable wall. Moreover, Mr. Oris, I advise you not to have such thoughts, unless—you want MIT's reputation to be completely ruined."

Wilson shrugged and said; the reason he asked the lawyer a few days ago was because he suspected that some profit-seeking people would have such small thoughts.

Alright, he was indeed depressed; he had always been proud of his excellent investment vision, but... he missed such a project.

"At the beginning, the Academic Committee didn't look favorably on this project, and was even unwilling to waste a single cent on this project. Backward laboratory, the strangest team configuration... I think we have no reason to go to Professor Xu for negotiations."

Someone sighed.

Others fell silent immediately. Who could have thought that such a team could really rank among the first-class superconducting thin film teams, and even have a trend of surpassing old-school laboratories.

They know that now those superconducting thin film laboratories are all putting their efforts into doing experiments.

"Hey, everyone, this is 300 million in funds." Oris knocked on the table, still a bit unwilling to give up.

Wilson squinted at the other party: "Mr. Oris, if I remember correctly, a few months ago, when everyone was discussing whether to add investment to Professor Xu, you cast a dissenting vote."

Oris was stuck immediately, helplessly leaning on the chair.

"I agree with Mr. Wilson's point of view, being an enemy of such a genius is not a wise choice."

Xu Qingzhou didn't know that he almost fell into a dispute of wrangling. Of course, even in this worst-case scenario, Song Xiaohua had already considered it before, so she added many terms to the patent transfer agreement.

In early April, Boston ushered in a continuous light rain, and Xu Qingzhou, who had been in seclusion for a long time, came to the laboratory again.

"Professor."

In the office, Carson and others were ready.

"Everyone, have you all finished reading the materials I sent out last night?"

"Yes, we know them by heart."

Carson nodded and said in a deep voice.

Nowadays, their sample JC performance is stable at 2.5×10⁴ A/cm².

According to model estimation, when the in-situ gradient doping technology iteration is successful, that is, forming a relatively perfect "sandwich interlayer" structure, the performance can be improved by at least 12%, which is 2.8×10⁴ A/cm².

He now feels a bit sorry for those laboratories working crazy overtime; no matter how they struggle, they can't stop the fate of being blown up.

On one side, Sun Simin and Ma Ersi were also full of energy.

"Very good."

Xu Qingzhou nodded, changed clothes quickly,

and led Carson and them to start a new round of experiments.

The overall progress of the project was a few days later than expected, because just doing the model and researching how to improve lattice strain took a week.

This thing is very important, and it can even be said that for now, controlling lattice strain is the key to breaking through superconducting performance.

Using the domino chain effect to explain, after pushing the first domino, the chain reaction transfers energy, but the spacing between dominoes determines the speed of collapse, meaning that the spacing between dominoes is the decisive factor for strain propagation.

Lattice strain also has the same effect; local lattice distortion caused by doping atoms is transmitted to the entire film through phonons. This distortion disturbs electron movement, which can increase resistivity, and can also improve critical temperature through phonon-mediated electron-phonon coupling.

Xu Qingzhou and Carson debugged the equipment, and Sun Simin and Ma Ersi were not idle, preparing precursors; everything was in an orderly manner.

Currently, the complexity of the experimental steps is at least ten times that of the first round of experiments, adding many, many steps.

The precursors were changed from the traditional Sn(CH) to Sn(NET) (diethylaminotin), and H plasma was also introduced to enhance the reaction, quantum-level interface engineering, pre-depositing a single layer of transition metal chalcogenide WS on the graphene surface, and additionally epitaxially growing topological insulator BiSe on the NBSN film surface...

It took 6 days for Xu Qingzhou and Carson to send 4 sets of samples, totaling 16 superconducting thin films, to the characterization testing laboratory.

The characterization test of the samples hadn't come out yet. On April 7th, Xu Qingzhou and Song Yao met the manager found by the headhunting company entrusted by Griffiths at a cafe outside Harvard Business School.
