Xueba's Sea of ​​Stars

Chapter 307 You're done!

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

After resisting the temptation, Wu Bin sent an email back 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 a two-dimensional material, people will naturally compare it with its "predecessor" graphene, and in the comparison, a major defect of graphene is infinitely magnified, that is, it has no energy gap and cannot be phased with silicon. Tolerance, which greatly limits its application in the semiconductor industry and optical devices and other fields.

But black phosphorus is different. To make a metaphor, if graphene is like a metal, then black phosphorus single crystal is inherently a semiconductor, 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 that.

[I wish you success in your research! 】

"Hey! Black phosphorus is 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 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."

"Thanks, is it convenient for you to let her come over now?"

"No problem, I'll call her later, I'll definitely be there tomorrow... Wait, if you're looking for a patent attorney now... In other words, it's done!?"

"Well, congratulations."

"Fuck! Fuck? Fuck!? 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. By then, as long as other laboratories repeat the success, graphene should be able to enter the public eye."

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

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

"Nonsense, you are lazy to get excited, someone has to get excited for you, hurry up and talk, where?"

"Dining in the cafeteria."

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

"I'm convinced of this guy..." Putting down his phone, Wu Bin took another bite of the braised beef noodles on the table.

At the beginning of the experiment, Wu Bin put all the remaining four talent points into the [Nano Monarch] talent, and it reached the fourth floor, and then in the subsequent research, Wu Bin raised two levels, but the two Point Wu Bin did not throw it into [Nano Monarch], but clicked it on the thermodynamic talent named [Tyrant] on the second page of physical talent.

After repeated experiments, Wu Bin finally used the ferromagnetic transition temperature found in iron germanium tellurium, a two-dimensional material characteristic, to successfully solve the problem of excessive surface area.

This is also the most troublesome problem in the mass production of graphene. It is necessary to know that graphene exceeding 5NM is not graphene.

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 the new technology lithium ion intercalation graphene thin layer, so that the ferromagnetic transition temperature of the sample is raised above room temperature.

In this way, the single-layer graphene grade prepared in this way does not have the problem that the graphene obtained by the mechanical method has a complete surface structure, but the size is extremely difficult to control, nor does the graphene obtained by the redox method have such a poor surface structure that it is outrageous. Fatal short board.

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

It can be said that the graphene produced by this preparation method solves the two problems of large-scale screening and packaging and transportation at the same time, and also takes into account environmental protection issues. When the redox method is used to produce graphene in large quantities, every gram of graphene produced will cost More than 200 grams of waste acid is produced, and it can be said that the finished product of recycling waste acid is even higher than the raw material.

But Wu Bin's improved CVD production method does not have this worry at all.

An excellent material that can be commercialized, this is the excellent graphene produced by the Wu-style preparation method!
'Tsk... I should think of a better name. Wu Bin couldn't help thinking while chewing the beef.

"I said, 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 very good. The beef noodles made in the cafeteria are quite delicious." Wu Bin took another mouthful while speaking.

After hearing this, Li Yan immediately cupped his hands and said, "It's amazing, a big boss is a big boss. Even if I didn't devote myself to materials science, I understand that your breakthrough can change the world if it's a small breakthrough."

"Shh... low key, low key, what are you shouting about?" Wu Bin ate his noodles after finishing speaking.

"Okay, okay, don't tell me if you don't say it. Here, here is the basic information of the patent attorney I found for you. Take a look. If you are satisfied, I will call her now."

"Oh good." After Wu Bin finished speaking, he took a nap and wiped his mouth, then picked up the paper on the table and looked at it.

"Hmm... graduated from Zheda University, majored in power engineering and engineering thermophysics, technical fields: materials, mechanical engineering, semiconductors, yes, is the threshold for patent attorneys so high?" Wu Bin looked at the information in amazement.

"That's not enough. I said that you found the best patent attorney company in the country. This lady named Cao Yu is also an outstanding attorney."

"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, that's her!"
