"Many things cannot be explained clearly in emails, and it is inconvenient to put them in emails. I will demonstrate it to you on the spot, and you will understand how amazing this thing is."
The meaning of Jc is the same. When the voltage on both sides of the conductor reaches a certain value, the current passing through the superconductor exceeds the critical value, and the conductor will exit the superconducting state.
"Let's make a deal."
Hearing this, the smile on Kleiber's face was a little bitter: "But how long do you think it will take for the industry to start to become interested in it?"
By then, there's no telling if the price of this material will come down.
Lu Zhou smiled and said in a relaxed tone, "Of course."
One of the more classic methods is to etch grooves on the surface of silicon carbide and use it as a substrate, on which graphene nanoribbons with a width of only a few nanometers can be formed.
Lu Zhou said in a relaxed tone: "The main costs are concentrated in the production of substrates. The cost of small-scale production is indeed high, but according to our research, as long as the production scale is expanded, its cost is not as difficult as we imagined. accept."
"You don't have to worry about the mass production of SG-1 wires. In fact, we have contacted relevant companies and the design of the production line has entered the final stage. In one year at the latest, we will be able to implement the production of SG-1 materials Production."
With that said, Lu Zhou nodded to Qian Zhongming, indicating that it was time to start.
Professor Kleiber raised his eyebrows, as if he understood what Lu Zhou was referring to.
By then, there's no telling if the price of this material will come down.
Lu Zhou smiled faintly and said, "We were inspired by the vapor deposition method. As for how we did it, please forgive me for not revealing it yet. I hope you can understand."
Professor Kleiber asked cautiously: "Can you show it to me?"
"Let's make a deal."
At least, it has far surpassed cuprate superconducting materials.
If you don't see enough profits, industry may never be interested.
Professor Kleiber raised his eyebrows, as if he understood what Lu Zhou was referring to.
After receiving Lu Zhou's instructions, Qian Zhongming pressed a few buttons on the computer next to him and operated the equipment to introduce liquid helium to the top of the glass cover.
And as long as the substrate is successfully obtained, it is equivalent to obtaining a mold for synthesizing this kind of wire, which can be used repeatedly in the laboratory or production line.
When designing the experiment, Lu Zhou referred to the method of the CNR Institute of Nanoscience and Technology, but instead of using silicon carbide, he used single-atom-thick metal rhodium flakes made by reducing the weak ligand polyvinylpyrrolidone and formaldehyde. , punch them after stacking, and then adjust their overlap angle.
"It's too early to be surprised now," Lu Zhou smiled faintly, looked at Qian Zhongming and continued, "Increase the voltage."
Almost at the moment when the ultra-low-temperature liquid helium comes into contact with the wire, the heat of the wire flows away at an incredible speed, and then quickly reaches the transition temperature, and the resistivity curve on the computer screen also slides to the bottom.
Even among the latest research results, the graphene nanoribbon synthesis technology jointly completed by the CNR Nanoscience Institute in Italy and the University of Strasbourg in France has cut the nanoribbon to a width of seven atoms.

Lu Zhou smiled lightly, but said nonchalantly: "This is not a market economy in the complete sense. The laws you mentioned do not fully apply here. It is not necessarily the market that guides the industry. It’s something else.”
Marveling at the molecular processing technology involved, and looking at the simulated images on the computer screen, Professor Kleiber finally couldn't help but ask: "How did you do it?"
The surprise could be clearly seen on his face.

Of course, while this may sound simple, it's not so simple in practice.
The meaning of Hc is that when the magnetic field intensity on the surface of the superconductor reaches a certain magnetic field intensity Hc, it will exit the superconducting state.

For example, how to make vertically stacked graphene nanoribbons and how to adjust the overlap angle between layers are all problems that must be solved.

In the simulated image, carbon atoms marked in green are closely stacked.
Superconductors have three critical parameters, namely critical transition temperature Tc, critical magnetic field strength Hc, and critical current density Jc.

Fortunately, the work was finally completed.

Although in his opinion, doing this is simply nonsense...
From an engineer's perspective, he can clearly see that maintaining this "SG-1" superconducting material at the superconducting transition temperature is far more difficult than maintaining the copper oxide material at the superconducting transition temperature. It's much easier at transition temperatures.

It turns out that it is much easier to manipulate micron-scale substrates than to fiddle with hexagons a few atoms wide.

This involves many complex methods and the tireless efforts of countless scientific research dogs.
Even among the latest research results, the graphene nanoribbon synthesis technology jointly completed by the CNR Nanoscience Institute in Italy and the University of Strasbourg in France has cut the nanoribbon to a width of seven atoms.
By then, there's no telling if the price of this material will come down.
Professor Kleiber asked cautiously: "Can you show it to me?"
At least, it has far surpassed cuprate superconducting materials.
Lu Zhou smiled faintly and said, "We were inspired by the vapor deposition method. As for how we did it, please forgive me for not revealing it yet. I hope you can understand."
In fact, Kleiber felt that this "hair" had such potential, but he didn't know how long he would have to wait for this day.
"OK."
Lu Zhou smiled faintly and said, "We were inspired by the vapor deposition method. As for how we did it, please forgive me for not revealing it yet. I hope you can understand."
However, even if there are existing research results for reference, difficulties still exist.
It turns out that it is much easier to manipulate micron-scale substrates than to fiddle with hexagons a few atoms wide.
Skillfully operating the equipment, Qian Zhongming followed Lu Zhou's instructions and increased the voltage applied to both ends of the wire.
After a moment of pause, Lu Zhou looked at Professor Kleiber and spoke.
If you don't see enough profits, industry may never be interested.
The surprise could be clearly seen on his face.
It turns out that it is much easier to manipulate micron-scale substrates than to fiddle with hexagons a few atoms wide.
"You don't have to worry about the mass production of SG-1 wires. In fact, we have contacted relevant companies and the design of the production line has entered the final stage. In one year at the latest, we will be able to implement the production of SG-1 materials Production."
Lu Zhou smiled lightly, but said nonchalantly: "This is not a market economy in the complete sense. The laws you mentioned do not fully apply here. It is not necessarily the market that guides the industry. It’s something else.”
Professor Kleiber's pupils shrank slightly.
However, even if there are existing research results for reference, difficulties still exist.
In the lateral structure, densely packed carbon atoms are arranged in a hexagonal shape in a space with a width of only a few thousand nanometers, just like a network woven with a six-grid pattern.
If you don't see enough profits, industry may never be interested.
Almost at the moment when the ultra-low-temperature liquid helium comes into contact with the wire, the heat of the wire flows away at an incredible speed, and then quickly reaches the transition temperature, and the resistivity curve on the computer screen also slides to the bottom.
Professor Kleiber raised his eyebrows, as if he understood what Lu Zhou was referring to.
It turns out that it is much easier to manipulate micron-scale substrates than to fiddle with hexagons a few atoms wide.
This involves many complex methods and the tireless efforts of countless scientific research dogs.
Lu Zhou smiled and said in a relaxed tone, "Of course."
After a moment of pause, Lu Zhou looked at Professor Kleiber and spoke.
After that, he continued to signal Qian Zhongming and called up the simulation image.
Although in his opinion, doing this is simply nonsense...
For example, how to make vertically stacked graphene nanoribbons and how to adjust the overlap angle between layers are all problems that must be solved.
In the lateral structure, densely packed carbon atoms are arranged in a hexagonal shape in a space with a width of only a few thousand nanometers, just like a network woven with a six-grid pattern.
The industry will not decide to produce a technology just because it is interesting enough, nor will it rush to update its production lines just because ITER needs to add an experimental reactor, unless the country where they are located can obtain enough profitable orders for them through the ITER organization.
With that said, Lu Zhou nodded to Qian Zhongming, indicating that it was time to start.
One day, high-tech companies such as Microsoft suddenly discovered that SG-1 materials can be used in the engraving of circuit boards, or other places such as supercomputing chips. The demand generated by the downstream industry pushed upstream companies to begin to expand this field. of production capacity.
"You don't have to worry about the mass production of SG-1 wires. In fact, we have contacted relevant companies and the design of the production line has entered the final stage. In one year at the latest, we will be able to implement the production of SG-1 materials Production."
Creber couldn't help but ask: "What about the cost?"
Fortunately, the work was finally completed.
This involves many complex methods and the tireless efforts of countless scientific research dogs.
At least, it has far surpassed cuprate superconducting materials.
Even among the latest research results, the graphene nanoribbon synthesis technology jointly completed by the CNR Nanoscience Institute in Italy and the University of Strasbourg in France has cut the nanoribbon to a width of seven atoms.
After a moment of pause, Lu Zhou looked at Professor Kleiber and spoke.
Lu Zhou said in a relaxed tone: "The main costs are concentrated in the production of substrates. The cost of small-scale production is indeed high, but according to our research, as long as the production scale is expanded, its cost is not as difficult as we imagined. accept."
Professor Kleiber asked cautiously: "Can you show it to me?"
After glancing at Kleiber, Lu Zhou continued: "In addition to these images, we observed its atomic distribution structure under a scanning tunneling microscope and drew a simulated image of the carbon atomic distribution based on these data."
In fact, Kleiber felt that this "hair" had such potential, but he didn't know how long he would have to wait for this day.
"Let's make a deal."
The meaning of Jc is the same. When the voltage on both sides of the conductor reaches a certain value, the current passing through the superconductor exceeds the critical value, and the conductor will exit the superconducting state.
In the longitudinal structure, the layers are stacked at slight angles, pulling out a slender columnar structure along the vertical direction.
This involves many complex methods and the tireless efforts of countless scientific research dogs.
Looking at the curve of resistivity changing with current, Professor Kleiber finally had a look of shock on his face.
