Thank you for your kindness, but I still have new directions to study, so I won't bother, and I wish you all the best 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 not reconciled, so he sent another email.

Are you sure? This time, we want to challenge the possibility of applying it to CMOS converters. 】

Black phosphorus is an allotropic form of phosphorus, and there are two kinds of structure: bulk and two-dimensional single crystal structure.

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

Homotopically two-dimensional materials, 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 is not compatible with silicon, which greatly limits its application in the semiconductor industry and optical devices.

But black phosphorus is different, to make an analogy, if graphene is like a metal, then black phosphorus single crystal is inherently a semiconductor, it can be easily "turned on" and "off"

That's why it can be used in converters.

But even if Professor Mars has a "showdown", Wu Bin still says the same thing.

[I wish you all the best in your research!] 】

"Gan! Black phosphorus or something is evil, and I will let you know that graphene is the king of materials in this era! ”

After suppressing the curiosity in his heart with cruel words, Wu Bin no longer continued to communicate with Professor Mars, anyway, the review has been approved, and his article will be published in the next issue of Nature

……

In a peaceful atmosphere, three months passed quietly, and on this day, when Li Yan had just finished his military class and was walking to the student union, he suddenly received a call from Wu Bin.

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

"Didn't I trouble you to help me find someone in charge of patent applications a while ago, and now that someone has found it?" Wu Bin's voice on the other end of the phone was slightly hoarse.

"Don't worry, your business is my first priority, and I have asked my dad to help you find a patent agent from Liu Shen Law Firm, which is the top patent company in the country."

"Thanks, can you let her come over now?"

"No problem, I'll call her later, I'll be there tomorrow...... Wait, if you're looking for a patent attorney now...... In other words, it has come to fruition!? ”

"Well, congratulations."

"! it? it!? Wait, wait, I'm sure, yes...... Is the mass production problem of single-layer graphene solved? ”

"Well, the verification experiment has been completed here, and after the patent application is successful, I will submit the manuscript to science, and as long as there are other laboratories that succeed in repeating it, graphene should be able to enter the public eye."

"! groove groove groove! So I'm witnessing history!? You wait, where are you now, I'll go. ”

"Well, why are you more excited than me?"

"Nonsense, you're lazy and excited, someone has to be excited for you, say it quickly, where?"

"Eat in the cafeteria."

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

"Serve this guy......" Put down the phone, Wu Bin took another bite of the braised beef noodles on the table.

At the beginning of the experiment, Wu Bin first smashed all the four talent points he had into the [Nano Monarch] talent, and pointed it to the fourth layer, and then in the subsequent research, Wu Bin upgraded it to two levels, but Wu Bin did not throw it into the [Nano Sovereign], but pointed it on the thermodynamic talent called [Tyrant] on the second page of the physics talent.

Later, in experiments again and again, Wu Bin finally successfully solved the problem of high surface area by using the two-dimensional material characteristic of ferromagnetic transition temperature found in iron germanium tellurium.

THIS IS ALSO THE MOST TROUBLESOME PROBLEM IN THE MASS PRODUCTION OF GRAPHENE, YOU MUST KNOW THAT GRAPHENE MORE THAN 5NM IS NOT GRAPHENE.

So after overcoming this most troublesome puzzle, the remaining problems are far less intractable.

Today, Wu Bin still uses CVD, but he uses a new technology to interlayer graphene with lithium-ion intercalation to increase the ferromagnetic transition temperature of the sample above room temperature.

In this way, the single-layer graphene grade prepared in this way has neither the graphene obtained by mechanical method, although the surface structure is complete, but the size is extremely difficult to control this problem, nor the graphene surface structure obtained by the redox method is so poor that it is a fatal shortcoming.

Even the graphene produced by CVD is extremely easy to oxidize in the air.

It can be said that the graphene made 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 the environmental protection issues, the original redox method will produce more than 200 grams of waste acid for every gram of graphene produced in a large number of graphene, and it can be said that the finished product of recycled waste acid is even higher than the raw material.

But Wu Bin's now improved CVD production method has no such worries at all.

An excellent material that can really be commercialized, this is the excellent graphene made by the Wu-style preparation method!

'Tsk...... I should come up with a good name. Wu Bin chewed the beef and couldn't help but think.

"I said, you will 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 canteen are very delicious." Wu Bin said and took another "suck".

After hearing this, Li Yan immediately arched his hand and said: "Awesome, the big guy is the big guy, even if I don't devote myself to materials science, I understand that your breakthrough is at best to rebuild the industry ecology, and at the big point, it is to change the world." ”

"Shh......h Low-key, low-key, what are you yelling about. After Wu Bin finished speaking, he ate the noodles again.

"Okay, okay, if you don't say it, don't say it, oh, this is the basic information of the patent attorney I found for you, you can take a look, if you are satisfied, I will call her now."

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

"Hmm...... Graduated from the university, master's degree in power engineering and engineering thermophysics, technical fields: materials, mechanical engineering, semiconductors, yes, is the threshold for patent agents so high? Wu Bin looked at the information and was amazed.

"That's not it, I said that I helped you find the best patent agent company in the country, and this lady named Cao Yu is also an outstanding agent in it."

"She has been working in Liu Shen Law Firm for 16 years, and has solved patent-related problems, and last year she was also an excellent agent of the judges of Samsung Huaguo Semiconductor Division, and she has also taken on a lot of international patent infringement disputes between multinational groups, and finally solved them beautifully."

"Okay, that's her!"
