Around the beginning of the year, Pablo · The Jarillo-Herrero laboratory has made quite outstanding achievements in graphene superconductivity research projects, opening up a new platform for the study of superconductivity.

That is, when the overlapping angle of two graphene sheets is close to 1.1°, the band structure will be close to a zero-dispersion band, resulting in the transformation of this band into a Mott insulator when it is half-filled.

At that time, this research result caused quite a stir.

Although in the eyes of many laymen, the superconducting transition temperature of 1 Kelvin is really not very good, but in fact the project is full of potential.

As to why, it is important to first understand a very basic concept, that is, the superconducting transition temperature is directly proportional to the carrier concentration of the material.

Therefore, theoretically, as long as the carrier concentration of the material can be increased, the upper limit of the superconducting transition temperature can be increased.

To make a very simple data comparison, the graphene download flow concentration under the above conditions is only 10^11cm^-2, but the transition temperature reaches 1K.

In contrast, the superconducting transition temperature of copper oxides is about 100 K, while the carrier concentration of equivalent two-dimensional materials is on the order of 10^14 cm^-2.

Even if you don't understand chemistry, you can intuitively feel the superiority of graphene materials in the field of high-temperature superconductivity research compared with traditional copper oxide materials.

As for how to increase the carrier concentration of graphene, there are many methods, which can be divided into N-type doping and P-type doping from the doping target, and metal doping, small molecule doping, substrate doping, lattice doping and so on from the doping material source.

And the advantage of graphene materials is also here.

Atomic-scale sheets of two-dimensional materials can be arbitrarily stacked and combined to form new structures, and these new structural materials often have new properties. And this near-infinite possibility also means infinite possibilities.

As for the disadvantage, it may be expensive.

However, for academic research, there is no need to consider such a thing as cost.

How to cut costs, how to productize, how to make a profit from it, those are all things that the industry needs to consider.

This time, however, Lu Zhou sincerely hopes that the industry will be a little faster and find a way to commercialize his research results.

The time left for him by the system was tight.

To build a "DEMO" nuclear fusion prototype by 2025, a more concise superconducting material in the engineering sense is essential.

After all, he could not have built this "DEMO" magnetic restraint device as big as the European Hadron Collider......

On the evening of the experiment, Lu Zhou invited Connie and Professor Chirick, along with his two assistants, to have a drink at the best bar in Palmer Square.

As for the money, it naturally comes from research funds.

Anyway, this research fund itself was paid by Lu Zhou himself.

"Honestly, why are you suddenly interested in superconducting materials? Doing research on superconducting materials, there is obviously no money for batteries. Ordering a cocktail, Professor Chirik, who was sitting next to Lu Zhou, asked.

Although there is nothing to discuss in the research direction, and there are people studying the unpopular direction, Lu Zhou used to study electrode materials, and now he suddenly turned to the research of superconducting materials, which really made Professor Chirick understand the reason for him to do so.

After all, although superconducting materials are not unpopular, the money is definitely not large.

Lu Zhou joked: "If I say it's for poetry and distance, do you believe it?" ”

"You've drunk too much," Chirik continued, looking at the bartender behind the bar, "Bartender, bring him a glass of Bloody Mary." ”

"Don't listen to him, Bloody Mary for Tequila Sunrise, that tomato juice you have to drink yourself," after a pause, Lu Zhou continued, "Well, to be honest, it's actually just because my experiments need to use a larger confined electromagnetic field, and the strength of the magnetic field that traditional copper oxide superconducting materials can provide in an engineering sense has reached its limit, so I have to find a way out of the new materials." ”

Professor Chirik: "For experiments in theoretical physics? ”

He seems to have heard the story of Lu Zhou and the 750GeV from somewhere.

Picking up the tequila sunrise placed on the bar, Lu Zhou slowly tasted it and replied ambiguously.

"Sort of."

"Okay...... Research for the sake of research, this reason is barely passed," shaking the glass in his hand, Professor Chirik made a helpless expression and raised his glass slightly, "I toast you for this feeling." ”

"Thank you."

also raised his wine glass, and Lu Zhou lightly touched the glass with him.

There's nothing fun about the bars at Palmer Square, and the customers here are mostly Princeton students or professors, except for the townspeople.

The kind of footage that usually appears in American dramas is difficult to see here, unless you go to a more biased place.

According to Connie, if you want something a little more exciting, you'll have to go to nearby Philadelphia.

But for Lu Zhou, the alcohol was enough to relax his tired nerves.

It is worth mentioning that the atmosphere here is not very warm, but the people are very welcoming.

Just as Professor Chirik was overwhelmed by the alcohol and slipped to the bathroom, perhaps noticing Lu Zhou sitting alone on the edge of the bar, a young and beautiful Asian lady came over and sat next to him, smiling and asking him for his phone number.

However, Lu Zhou quickly recognized that this guy seemed to be a student who had taken his own class, and he had left his phone number and email address on the blackboard more than once.

Obviously, there was no way she didn't know her phone.

Although I don't know what excitement she is looking for, most of the time she wants to have fun with herself.

After being exposed by Lu Zhou, a surprised expression appeared on her face, and then she walked away......

Playing frantically until almost the early hours of the morning, a group of drunken old men went back to their respective homes after crossing the street.

The next day, Star Technology North America sent a professional team of lawyers from Philadelphia to help solve the patent application problem.

Only after obtaining the patent number can the paper be published.

If this order is reversed, it is likely that the patent application will not be approved due to novelty issues.

In order to supervise the completion of the patent number application as soon as possible, the CEO of the North American branch, White Sheridan, personally came to visit.

Taking over the completed patent application materials from Lu Zhou's hand, Xie Lidan glanced at the patent description and couldn't help but say.

"Seriously, aren't you thinking about going public?"

Lu Zhou: "Listing? ”

Sheridan earnestly persuaded: "That's right, if we just rely on patent income, except for a one-time buyout license, we will make a profit of less than $100 million a year." But if you are listed on the NASDAQ board, with our market share in the field of lithium-sulfur batteries and the future development potential of the new energy industry, you can become a billionaire in less than a year. ”

I have to say that it sounds like it sounds attractive.

However, hearing the word billionaire, Lu Zhou just smiled and said indifferently: "The market value is all virtual, if it can all be turned into cash, I can consider it, but if not, I don't want to have a board of directors to make a report every time I set up a project." ”

His original intention of establishing Star Technology was to facilitate his own focus on research, and if he violated this original intention, he would put the cart before the horse.

As for what billionaires......

To be honest, if it was pocket money, he didn't know how to spend the hundreds of millions of dollars in his account.

"Okay...... Although I don't think even if you have a 1% stake, there is absolutely no fool who will stop you from experimenting. ”

Sheridan made a helpless expression.

There are really not many people who still hold such stubborn ideas in this era.

However, he has nothing to complain about.

After all, even though Lu Zhou has a strong desire to control the ownership of the company, the salary offered to him is quite generous.

That reason alone was enough to dispel his superfluous thoughts.
