Xueba's Sea of ​​Stars

Chapter 193 Worth a try

[Nano Monarch]: Can understand semiconductor physics, electronic materials, microelectronic devices and other fields more thoroughly.

'That's it! '

This standard material physics BUFF will definitely help him in terms of graphene.

Although Wu Bin really wanted to fill up this talent right away, but after thinking about it, he resisted the urge to finish reading all the talents.

There are still four remaining physical talents on the second side, which are unsurprisingly the four powerful BUFFs of [Theoretical Mechanics], [Quantum Mechanics], [Electrodynamics] and [Thermodynamics and Statistics].

However, different from the previous three talents, there are even finer branches under the four talents of the Four Great Mechanics.

For example, under [Theoretical Mechanics], there are three branches of talents: dynamics, statics and kinematics.

In Wu Bin's view, these physics disciplines actually influence each other. For example, the object in theoretical mechanics mainly refers to the rigid system, and when the deformation of the object cannot be ignored, it becomes the mechanics of deformable bodies such as material mechanics.

But while influencing each other, they are independent of each other, which makes it hard for Wu Bin to imagine how these independent subjects will collide in his brain after all his talents are maxed out... No, it should explode.

After thinking for a while, Wu Bin decided to click [Nano Monarch] first, after all, it is the most helpful for his current system tasks.

However, when Wu Bin wanted to go down, he froze.

'Two talent points! ? '

On the second side of talent, Wu Bin not only couldn't continue to enjoy the thrill of getting two layers of talent with just one talent point on the first side, but even doubled it!It takes two points to order a layer.

'This is going to go to the Year of the Monkey! '

However, the talent B level on the second page is indeed high. If the buff strength is high enough, it is possible to change the world if you fill it up. It is understandable to be harsh.

After persuading himself, Wu Bin took a deep breath and spent 4 talent points to order two layers of [Nano Monarch].

"No wonder the system rewarded 30 talent points so generously when I was promoted to level 5, so it was waiting for me here..."

After clicking on his talent, Wu Bin stopped worrying about it and plunged into the research of graphene.

Because at the moment when the two layers of [Nano Monarch] were lit up, new inspirations began to burst out in his mind such as suspension, activated carbon, expanded graphite, etc.

After successfully applying to Feng Jinhui, Wu Bin began to produce graphene by CVD, that is, chemical vapor deposition.

The principle of the chemical vapor deposition method is that the reactants undergo a chemical reaction under high temperature and gaseous conditions, and the resulting solid substance is deposited on the surface of the heated solid substrate to obtain a thin film material.

The principle is very complicated to explain, but through experiments, it is clear at a glance.

To put it bluntly, hydrogen gas is passed through one end of a tube, and the other end is evacuated, and when gas such as methane is passed through at about [-] degrees, graphene will grow on the copper foil.

Finally, just transfer it to a silicon wafer.

However, the number of graphene layers produced in this way is far more than ten layers, which is the so-called defective product.

It is far from a real single-layer two-dimensional material (less than five layers).

The method of replacing the substrate material has been tested by many people and written papers. Wu Bin has no new ideas at present, but when he enlightened his talent just now, the word radio frequency catalysis jumped out of his mind.

This is a processing method that can increase yield, but the carbides and amorphous carbon produced in the process will affect the quality of graphene.

'If a non-vacuum CVD technology is used to make polycrystalline Ni film, the gas phase precursor used in the traditional CVD process can be changed, and liquid ethane can be used as the precursor material instead. Selective growth of single-layer graphene nano-thin layer materials. '

'Worth a try! '

Wu Bin, who came up with this idea, began to collect data. After the theory was established, he would go to Professor Liu to apply for a project.

With motivation, Wu Bin was even more obsessed with staying in the laboratory for research, and soon, a week passed.

"Wu Bin... don't you think it's time to get your hair trimmed?" Lin Ziqi, who just came to the laboratory after class, pointed to Wu Bin's head that was almost turning into a bird's nest.

"Well... I'll cut it after I finish reading this paper." Wu Bin replied without raising his head in front of the computer.

"That's what you said yesterday..." Lin Ziqi sighed, "Let's find a better reason to perfunctory me."

"Cough...really?" Wu Bin smiled awkwardly.

"Listen to her, Wu Bin, you should go for a walk, there are some things you can't figure out just by staying in the laboratory." Feng Jinhui turned to look at Wu Bin and said.

"Huh..." Wu Bin heaved a sigh of relief after hearing this, scratched his hair and nodded, "Okay, then I'll go back to the dormitory to take a shower, I'm about to vomit after eating instant noodles and bread for a week, I'm going out to eat today Done."

"That's right, work and rest... Forget it, pretend I didn't say it."

There are a lot of busy people in the lab, and researchers like Feng Jinhui have to stay in the lab to record all kinds of data once they have a project.

Most people will become dull-eyed after passing through this boring experiment period, and they will jump out word by word when they see people talking, anyway, it will highlight a "mourning"

However, the higher the intensity of study, the brighter Wu Bin's eyes became. Even though he didn't find anything he needed from the thesis after spending a whole day, he was still in a good mood and continued to study the next one with great joy.

Feng Jinhui and his fellow researchers have never seen this kind of seriousness and a scientific attitude that doesn't know what a "mentality collapsed" is.

Even now Feng Jinhui has begun not to regard this freshman as a rookie who came to practice, but as a colleague, because as long as it is a question about physics, Wu Bin's knowledge is involved. Time can often give him a lot of inspiration, making him forget that the Xinnen in front of him is still a freshman.

Cycling back to the dormitory, Wu Bin found that Li Yan and Chen Anzhi were both in the dormitory, so he greeted them.

"Boss, are you willing to come back, the laboratory is so fun?" Chen Anzhi put down his phone and looked at Wu Bin and asked.

"Yeah, it was quite fun, so you can look forward to Dawu's class." Wu Bin replied while taking off his clothes.

"Why did I hear several seniors say that Dawu taught the class to kill us..." Chen Zhi'an looked blank.

"Do you dare to learn from his feelings?" Li Yan, who was making a watch at this time, turned around and reminded Chen Zhian.

Chen Zhian nodded: "That's right... After all, I'm just a mere human being."

Wu Bin didn't bother to quarrel with them after listening, so he took clean clothes and underwear and went to take a shower.
