Chapter 307 Done!

[Thank you for your kindness, but I still have new directions to research, so I won’t bother you. I wish you success in your research. 】

After resisting the temptation, Wu Bin replied an email to Professor Mars.

But Professor Mars on the other end of the computer was obviously unwilling to give in, so he sent another email.

【you sure? This time we are going to challenge the possibility of applying it to CMOS converters. 】

Black phosphorus is an allotrope of phosphorus, with two types of structures: block and two-dimensional single crystal structure.

As a member of the two-dimensional material family, black phosphorus, like graphene, has many excellent properties of a two-dimensional single crystal structure. The most exciting part is that it can prepare ultra-thin black phosphorus, which some people call For [phosphorene]

As both two-dimensional materials, people will naturally compare it with its "predecessor" graphene. In the comparison, a major flaw of graphene is infinitely magnified, that is, it has no energy gap and cannot interact with silicon. capacity, which greatly limits its application in fields such as the semiconductor industry and optical devices.

But black phosphorus is different. For example, if graphene is like a metal, then black phosphorus single crystal is a semiconductor by nature, and it can be easily "turned on" and "turned off"

And that's why it can be used on converters.

But even if Professor Mars had a "showdown," Wu Bin would still say the same thing.

[I wish you success in your research! 】

"Gan! Black phosphorus and everything else are evil. I will let you know that graphene is the king of materials in this era!"

After suppressing his inner curiosity with harsh words, Wu Bin stopped communicating with Professor Mars. Anyway, the review has been passed and his article will be published in the next issue of "Nature"

…

In a peaceful atmosphere, three months passed quietly. On this day, when Li Yan was walking to the student union after military class, he suddenly received a call from Wu Bin.

"What's wrong?" Li Yan answered the phone and asked.

"Didn't I trouble you to help me find someone responsible for patent applications a while ago? Has the person been found now?" Wu Bin's voice on the other end of the phone was slightly hoarse.

"Don't worry, your matter is my first priority. I have asked my father to help you find a patent attorney from Liu Chen Law Firm. This is the top patent company in the country."

"Thank you. Would you like to ask her to come over now?"

"No problem, I'll call her later. She'll definitely arrive tomorrow... Wait, if you find a patent attorney now... In other words, you've got results!?"

"Well, congratulate me."

"What the hell! What the hell? What the hell!? Wait, wait, let me make sure... is the problem of mass production of single-layer graphene solved?"

"Well, I have completed the verification experiment here. After the patent application is successful, I will submit it to science. As long as other laboratories repeat the success, graphene should be able to enter the public eye."

"Holy shit! Damn shit! So I'm witnessing history!? Wait, where are you now? I'll go there."

"As for that, why are you more excited than me?"

"Nonsense, you are too lazy to get excited. Someone has to be excited for you. Come on, come on, come on, where are you?"

"Eat in the cafeteria."

"Okay, I'll be there in 10 minutes." After saying that, Li Yan hung up the phone.

"I'm done with this guy..." Wu Bin put down his phone and took another bite of the braised beef noodles on the table.

At the beginning of the experiment, Wu Bin first poured all four of his saved talent points into the [Nano Monarch] talent, raising it to the fourth level. Then in subsequent research, Wu Bin upgraded it two more levels, but these two Wu Bin clicked it instead of throwing it into [Nano Monarch], but clicked it on the thermodynamics talent named [Tyrant] on the second page of the physical talent.

In subsequent experiments again and again, Wu Bin finally successfully solved the problem of excessive surface area by using the ferromagnetic transition temperature found in iron, germanium and tellurium, a two-dimensional material feature.

This is also the most troublesome problem in the mass production of graphene. You must know that graphene is not considered graphene if it exceeds 5NM.

So after overcoming this most troublesome problem, the remaining problems are far less difficult.

Today, the preparation method used by Wu Bin is still CVD, but he uses new technology to intercalate thin graphene layers with lithium ions, which increases the ferromagnetic transition temperature of the sample above room temperature.

As a result, the single-layer graphene level prepared in this way neither has the problem that the surface structure of graphene obtained by mechanical method is complete, but the size is extremely difficult to control, nor does the surface structure of graphene obtained by redox method is so poor that it is appalling. Fatal shortcoming.

Even the problem that graphene originally produced by CVD is extremely easy to oxidize in air has been solved.

It can be said that the graphene produced using this preparation method simultaneously solves the two problems of large-scale screening and packaging and transportation, and also takes into account environmental issues. When the original redox method was used to mass-produce graphene, each gram of graphene produced would More than 200 grams of waste acid is produced. It can be said that the finished product of waste acid recovery is even higher than the raw material.

But Wu Bin's improved CVD production rules don't have this worry at all.

An excellent material that can truly be commercialized is the excellent graphene produced by the Wu-style preparation method!

‘Tsk… I should think of a better name. ’ Wu Bin couldn’t help but think while chewing beef.

"I said, why don't you just eat a bowl of beef noodles for such a big happy event?"

At this time, Li Yan's voice suddenly sounded from behind Wu Bin.

"It's not that good. The beef noodles made in the cafeteria are quite delicious." Wu Bin said and took another mouthful.

After hearing this, Li Yan immediately handed over his hand and said: "Awesome, the boss is the boss. Even if I have not devoted myself to materials science, I still understand that your breakthrough will reshape the industry ecology at a small scale, and change the world at a big scale."

"Shhh... low-key, low-key, what are you shouting about." Wu Bin finished speaking and ate some noodles again.

"Okay, okay, if you don't say it, don't say it. Here, here are the basic information of the patent agent I helped you find. Take a look at it. If you are satisfied, I will call her now."

"Oh, okay." After saying this, Wu Bin opened his mouth and wiped his mouth, then picked up the paper on the table and read it.

"Hmm... graduated from Zhejiang University, master's degree in power engineering and engineering thermophysics, technical fields: materials, mechanical engineering, semiconductors, okay, is the threshold for this patent agent so high?" Wu Bin looked at the information and was amazed.

"That's not the case. I told you that the company I found for you is the best patent attorney company in the country, and this lady named Cao Yu is also an outstanding attorney there."

"She has been working at Liu Chen Law Firm for 16 years. She has solved many patent-related issues. Last year, she was rated as an outstanding agent by Samsung's Huaguo Semiconductor Division. In addition, she has dealt with international patent infringement disputes between multinational groups. She also took on many cases and solved them beautifully in the end.”

"Okay, then it's her!"
