Black Technology Refresher Manual

Lu Yin: "As the experiment progresses, the abnormalities of some parameters become more obvious. I know that, but I don't want to give up until the results come out." She shook her head and said with a pleasant face, "Tell me about your thinking."

Sheng Mingan: "Do you know anything about arc thermal plasma?"

"You mean thermal plasma? Graphene preparation?" Lu Yin pondered for a moment, then said, "I don't know much, if you don't mind? Let's talk about it first—let's go outside first?"

The two moved outside the laboratory to extend and discuss the idea of ​​arc thermal plasma? Until late at night, the lights of the Black Gold Technology Building were almost completely extinguished.

In the small meeting room outside the laboratory, brightly lit, Sheng Ming'an vaguely said: "...Magnetic arc plasma? Try to obtain a plasma with large volume and uniform parameters."

Lu Yin couldn't help yawning, and drank more than half of his black coffee trying to refresh himself.

Sheng Ming'an: "Why don't we talk about it tomorrow?"

Lu Yin hasn't had much rest in the past few days, and staying up all night is even more normal. He probably won't be able to hold on now.

Lu Yin apologized embarrassedly: "Then we can talk tomorrow, but I understand what you mean, and I think it's feasible."

Sheng Mingan packed up the drafts, and Lu Yin followed him and got up to leave, but when he reached the door of the laboratory, Sheng Mingan suddenly said: "I want to continue to improve my plan, and I need to borrow the equipment from the laboratory."

The laboratory is an important place for technology companies, and access is usually restricted. Even if you work overnight, in addition to monitoring almost everywhere, you also need the permission of the team leader?

Lu Yin said, "I remember." After saying that, he waved his hand and left.

Sheng Mingan stayed in the laboratory, and they were the only ones. Facing those silver-white icy machines, the surroundings were empty and silent. If it were an ordinary person at this time, he would feel a little bit lonely.

But Sheng Mingan has long been used to it.

In his previous life, he always stayed alone in the laboratory. What accompanied him was the faint sound of countless mechanical operations. He was obsessed with the mystery and unknown in the microscopic world, and never felt lonely.

There is an experimental detection device in the laboratory of Heijin Technology, which can not only realize the insertion of atoms in the crystal lattice, but also detect the superconducting properties of materials at the same time, accurately analyze the superconducting wave state of any material used in the experiment and present Output data, graphs, etc.

All in all, a very functional device.

Sheng Ming'an is going to do an experiment to find graphene superconductivity. In fact, it is a replica of an experiment that two universities in Tohoku and Tokyo jointly completed last year to insert atoms into a lattice to discover superconductivity.

The experiment is very simple. Insert calcium atoms into the lattice between two layers of graphene. The structure is similar to a sandwich biscuit, and superconductivity can be achieved.

He first designed the lattice insertion structure on the software, calculated all the data and quickly passed the design plan, and then carried out experiments according to the plan, and successfully obtained the graphene calcium atom-graphene structure.

The next step is to test the superconductivity of this structure and obtain usable data for analysis.

While waiting, the phone rang.

Sheng Mingan picked up the phone and saw that it was Chen Jingqiu calling, he was a little puzzled? Why are you still calling so late? What happened?

He? Connected to the video call?: "Chen Jingqiu."

Chen Jingqiu in a white coat and a mask appeared on the phone screen. He hooked the top of the mask and pulled it down, revealing light-colored lips and fair chin.

"What happened?" Sheng Mingan asked.

"I can't find you if I have nothing to do?" Chen Jingqiu pulled up a chair and sat down, with his mobile phone on the stand and his elbows on the table, stirring his teacups one after another. "Still in the lab?"

"Yeah. I'm doing an experiment on graphene superconductivity." Sheng Ming'an looked at Chen Jingqiu's background, seeing that the environment is also a laboratory: "Are you staying overnight?"

Chen Jingqiu smiled, raised his teacup and touched Sheng Mingan from the air: "I'm watching a material synthesis reaction, just collect images and data frequency every once in a while, it will take about seventeen or eighteen hours."

Sheng Mingan: "So you're bored now?"

Looking for video chat with him because of boredom?

"No."

"Then why are you videoing me in the middle of the night?"

"Because I miss you."

"..."

Sheng Mingan raised his eyes to look at the video window. He didn't know whether it was the illusion of lighting or the beauty function added to the video software. He suddenly felt that Chen Jingqiu was very handsome.

His aesthetics are quite normal, and he can get his face when he first saw Chen Jingqiu, but he has always admired Chen Jingqiu without any special preference.

At this moment, he was infested by Chen Jingqiu.

Although he came back to his senses quickly, it was undeniable that his heartbeat accelerated at that moment. Sheng Mingan raised his hand to his forehead, blocking their gaze, and responded vaguely.

When Chen Jingqiu saw that Sheng Mingan was still evading and refusing, he felt melancholy, so he took the initiative to change the topic: "I saw that Lu Gong in your team made a post on Moments and praised you for your hard work and initiative to work overtime. That's when I realized that you were going to stay up all night. So make a video call? Stay with you."

Sheng Mingan exited the video and entered Moments, and sure enough, he saw the Moments posted by Lu Yin, with a photo of him experimenting.

In the photo, they are wearing white coats in the research institute, holding a piece of graphite with one hand, the black graphite and their fingers seem to glow under the light.

Lu Yin's usual hobby is photography, so she captured Sheng Ming'an's cool and cool demeanor by taking random photos.

Sheng Mingan stared at the photo for a long time, and always felt that something was wrong, him? He looked up, glanced at Chen Jingqiu, and felt that something was wrong——

"Why do you have Lu Yin's WeChat?"

Chen Jingqiu paused for a moment, then smiled: "I know Mr. Ding from Heijin Technology. He once had a meal, and with his contact information, there was Lu Gong at the dinner. Added the number, I didn't expect you to enter the black gold technology so coincidentally later."

Sheng Mingan was dubious: "Really?"

Chen Jingqiu laughed and said, "Otherwise, from what channel should I add Lu Gong's contact information?"

Heijin Technology is in Jiangsu Province, and Chen Jingqiu is in Sichuan Province. The two places are thousands of miles apart. Unless they have met and become acquainted at work, it is really difficult to add contact.

After thinking about it so carefully, Sheng Ming'an believed Chen Jingqiu's words.

While speaking, Sheng Mingan suddenly raised his hand as a pause gesture, stood up and said, "The data on superconductivity performance is out, I'll go and have a look first."

Chen Jingqiu: "Go? Let's go."

They watched Sheng Mingan leave the camera range, and after leaving, he did not return within two or three hours.

They are both students of HKUST, and they are also interns in the research institute. Chen Jingqiu understands the busyness of Sheng Mingan's experiment, so he lowers his head and quietly makes his own experiment plan and completes the process plan. This experiment is not related to his graduate thesis. related.

The mobile phone is placed in front, and the video call? is still going on. A small piece of iron, an invisible electronic? Data connects two places and two people who are thousands of miles apart.

Chen Jingqiu would occasionally look up at the phone, looking for Sheng Mingan's figure, and sometimes he would be fascinated by it.

It seems that for them, the existence of Sheng Ming'an is the only color and fun in their "boring and lengthy" academic research.

Sheng Ming'an in this laboratory is carefully recording data, observing the conductivity of the structure, analyzing the spin orientation of electron pairs, looking for and verifying the p-wave state of graphene electron pairs.

What is a p wave state?

This needs to start with the characteristics of superconductors. In traditional superconductors, every two electrons form a "Cooper pair" to produce a non-resistance effect, which is the superconductivity pursued by human beings.

The pairing method of the two electrons in the Cooper pair determines the type of superconductor, and one of them points upward and downward respectively. The two electrons moving in parallel are called s-wave superconductors.

The s-wave superconductor is the most conventional type of superconductor, and its superconducting material is usually iron, mercury, etc.

Subsequently, people discovered d-wave superconductivity and p-wave superconductivity. Among them, p-wave superconductivity has been in a research dilemma since its discovery, because the main superconducting material is a crystal that is too large to study The strontium ruthenate crystal material has so far been unable to confirm the type proof of the existence of this state, as well as in-depth research.

But at the end of last year, a paper published in Nature by a Cambridge University research team showed that coupling graphene with cuprate superconducting materials can stimulate the superconductivity of graphene itself, and It is analyzed that the superconductivity is probably a p-wave state.

In other words? In other words, the superconductivity of graphene is probably the p-wave state.

If it can be confirmed that graphene produces p-wave superconductivity, then graphene can be used as a complete and large-scale development to study superconductivity, explore superconductivity and its devices, and so on.

Sheng Mingan just wanted to study the p-superconductivity of graphene and gain a deeper understanding of the superconductivity of graphene.

They? Conducted two experiments at the same time, and carefully entered the data into the software to make a graphene-related electronic? Logarithmic model, a model in which countless hexagonal carbon atoms? Jump off the screen.

Sheng Mingan quickly saved the model, and then proceeded to the next set of data modeling.

The laboratory was so quiet that only the muffled sound of machinery was left, and time passed silently. Sheng Mingan always stood in front of the experimental device, without looking back at his mobile phone. He was so engrossed that he forgot about him and Chen. Shocking communication.

Chen Jingqiu sometimes gets up to collect data and images, but most of the time he stays in front of the screen, writing and working.

According to all the collected data and models, Sheng Ming'an first theoretically calculated the tunneling spectrum and average current of the graphene p-wave superconductor.

Under certain conditions, graphene itself can stimulate superconductivity.

This has always been a universally believed truth in the physics academic circle, but it is a pity that the superconductivity of graphene cannot be sustained.

After completing the complex theoretical calculation and statistics, Sheng Mingan looked up at the images collected by the scanning tunneling microscope device. Each image has very obvious electrical characteristics of materials.

He? Ready to analyze these electrical characteristics, from which the superconductivity that belongs to graphene is precipitated.

When Sheng Mingan was collecting image data, he remembered Chen Jingqiu who was on the opposite side of the mobile phone video communication, and hurriedly looked back, and was surprised to find that the communication was still going on.

And Chen Jingqiu, who was immersed in writing and calculating, seemed to be aware of it, and happened to look up and see Sheng Mingan who was picking up the phone.

"It's over?" Chen Jingqiu put down his pen and asked.

"It's not that fast." Sheng Ming'an found an angle where he could look up and look at each other, put his phone down, pointed to a series of devices and said, "It's not difficult to prove that graphene has superconductivity, but the difficulty lies in the superconductivity of graphene." What exactly is conductivity and how to prove it.”

This angle allows Chen Jingqiu to see a part of the image collection. He became a little interested and asked, "Is this the tunnel spectrum?"

Tunneling spectrum, as the name implies, is the phenomenon of electron shuttle tunneling.

Sheng Ming'an can't stop talking about these things, especially the listener? Or let him? The very relaxed Chen Jingqiu.

He said: "This experiment can prove that graphene itself has superconductivity, and it will excite superconductivity after coupling with cuprate oxides, and the results will be observed and recorded. Most cuprate oxides are superconductors." , and it is a known superconductor with obvious superconducting properties. Both can be observed by scanning tunneling microscopy? Superconductivity after coupling..."

Because the superconductivity of cupric acid oxide is known, it is only necessary to calculate the superconductivity of the part of cupric acid oxide, and the rest is the superconductivity of graphene.

As a result, there are three possibilities: Graphene does not have superconductivity.Graphene possesses the same superconductivity as copper oxide.Graphene stimulates superconductivity, which is different from that of cuprate oxide?.

The result is the third.

Sheng Mingan carefully recorded the images of the electron pairs he observed, "Observing the tunneling spectrum is to observe the pairing mode of the electron interaction, and their states will change with different types of superconductivity. Therefore, the observation of superconductivity The electrons in the spin state? Then the superconductivity of the superconductor can be analyzed—"

At the critical moment of calculation, Sheng Ming settled down, held his breath, concentrated his attention, cautious attitude, and tense spirit, but he saw that a coordinate system was quickly established on the light screen, and above the coordinate system were images of mountain peaks. .

The image shows a gradient of red, yellow, green and blue from top to bottom. It is quickly established, automatically saved, then collapsed and disappeared, and other electronic paired images are reconstructed.

Image synthesis collects new data, and the data is calculated to establish a new superconducting structure model.

Sheng Mingan stopped typing on the keyboard, picked up the mobile phone, pointed at the screen, pointed to the stable Cooper and said to the structural model: "This is the electron pair of the copper oxide oxide, and their spin states are all controlled. It is observed that it is a d-wave state with an angular momentum of 2. The other state does not belong to cupric acid oxide?, indicating that it comes from graphene."

"This experiment verifies that graphene is intrinsically superconducting. I copied the experiment of the research team at the University of Cambridge, but this experiment did not confirm the superconducting type of graphene. I only guessed that it might be p-wave superconductivity. But about p-wave Very little research has been done on superconductivity—”

Sheng Mingan paused at this point.

He? He wanted to say that the type of p-wave superconducting state proves that there are strontium ruthenate crystals, but the superconducting state of strontium ruthenate crystals will be determined in a few years. It may be a new type of superconducting g-wave superconducting, and Not p-wave superconducting.

So only graphene is left. This type is likely to prove the existence of p-wave superconducting state.

But it's troublesome to explain, so Sheng Ming'an won't talk about it.

"My experiment is over."

Sheng Mingan made simple records and summaries in his draft notebook.

The author has something to say: 1. There are few updates these days, because there is very little information about graphene, and most of the detailed papers focus on the research of graphene-derived materials rather than the scale extraction and superconducting properties of graphene itself.

Basically, if you write a few words or a word, you have to check the information, (the difficulty is that there is no information to check), so the update is invincible and slow

2. The network is often disconnected these days. I just found out that I forgot to set the password after restarting before, and opened WIFI, so I tossed a bit.

3. In addition, I have difficulty breathing these few days, I can’t breathe, my brain is a little lack of oxygen, I will go to the pharmacy to buy an oxygen bottle (I don’t know if it is sold)

The above is the reason for the lack of updates.
