Super Xueba: Start With A Low Control Score!

Chapter 491: If Laozi is not allowed to play on the chessboard, he just throws the chessboard off!

Hey-hey!

If the old man guessed correctly.

It is estimated that there are a lot of people, but I didn’t understand the above essay questions, because the old man didn’t understand it either (っ///c).

but……

Just don’t understand it.

College physics is hard enough, and the above paper is hundreds of times deeper than college physics!

They are not of the same grade at all.

Not to mention the old man.

Even if it is a physics major.

If you don’t have a doctoral level for graduate students, and you have some research on graphene, you probably won’t understand it.

So what does it specifically talk about?

If Wang Xuan is here, his eyes will light up immediately, and then he will be ecstatic, and even shocked.

Just because…

Let’s not talk about it based on strain electronics.

Among them, the perfect graphene is intentionally twisted by θ degrees to create a new type of corrugated structure. This is actually similar to the magic angle graphene studied by Wang Xuan, or even homologous.

Although this is unexpected, it is reasonable.

After all, Jiang Nan didn’t know much about graphene in the past.

Later, on the one hand, I read a lot of physics books, and I have a good understanding of the properties of graphene.

On the other hand, I had an in-depth exchange with Wang Xuan. The graphene knowledge that Wang Xuan mastered was not only learned by Jiang Nan, but even more deeply.

It can be said like this.

Jiang Nan’s knowledge of perfect graphene is based on Wang Xuan’s research.

nature!

He was greatly influenced by Wang Xuan.

Therefore, the new characteristics of perfect graphene are discovered this time, which is based on the principle of magic angle graphene.

But the difference is…

Wang Xuan’s research direction is inclined to the phenomenon of magic angle double-layer and even triple-layer graphene antimagnetic superconductors.

After Jiang Nan passed a lot of experiments.

A specific kink angle is directly given to create a new corrugated structure of perfect graphene, which can free up a lot of internal space and create smart electronic components.

Um!

If you still don’t understand.

to be honest.

It is possible to fabricate carbon-based transistors and logic gates through perfect graphene kink θ degrees.

So what does this carbon-based transistor and logic gate do?

They are the basis for making chips.

To know in today’s world.

All chips are silicon-based chips.

Although silicon-based chips are very powerful.

But it has reached the limit of traditional semiconductor technology.

For example, the running speed, its own weight and the volume occupied, etc., are difficult to make further breakthroughs.

But once Jiang Nan’s paper is okay, he can use it to make a legendary silicon-based chip.

Everyone has heard of carbon-based chips!

Many countries are doing ideas and researches, but there have been no major breakthroughs, and it is even difficult to make progress.

But in everyone’s imagination.

Because graphene is a nanomaterial, it is the thinnest and strongest material found so far.

Once it is made into a transistor, it will be an ultra-micro transistor, and further it will be a micro-shaped chip, which will be about 100 times smaller than a traditional silicon-based chip.

Gee!

Today’s chips are small enough, but what is the concept that carbon-based chips are 100 times smaller?

That is simply invisible to the naked eye, okay!

But small and small.

But its nature is to sling silicon-based chips, which is not only more environmentally friendly, more sustainable, and consumes less energy.

And it can make the computer faster.

Increase the running speed of our mobile phones and computers by ten times, a hundred times, or even thousands of times (ง•̀_•́)ง.

Besides.

There is also a crucial point.

That is the manufacture of silicon-based chips.

Need to use a very critical instrument-high-end lithography machine, also called 5nm lithography machine.

And this so-called 5nm lithography machine cannot be produced with the current Dongyun technology.

Because it’s actually too complicated.

As a product that integrates the strengths of global resources, it is one of the best representatives of human technology condensed together.

The components of an EUV lithography machine can reach as many as 100,000 if they are finely divided.

Assemble it like a huge cuboid box. Almost every internal part of such a complicated instrument requires high quality and high precision.

Gee!

Unless Dongyun’s technology is developed for another half a century.

otherwise……

It is impossible to make a high-end lithography machine.

Maybe some big conferences say…

We can’t make it, we can buy it with money!

Um!

The old man thought the same at the beginning.

After all, although the output of EUV lithography machine is not large a year, it is no problem to produce dozens of units.

As for the price?

The current market price is 700 million Dongyun coins.

Actually it may be higher.

But at most it is more than 1 billion Dongyun coins.

And how much more than 1 billion Dongyun coins?

For ordinary people, that is definitely an astronomical figure, but for a country, more than 1 billion is not too much.

But this is not the point.

The point is that you want to buy, but others don’t sell it!

Not to mention more than 1 billion Dongyun coins, even if you spend 10 billion, people will not sell it to you.

Just because…

The relevant supply chain of lithography machines is banned for Dongyun. At the same time, subject to the restrictions of the international patent law, all relevant companies dare not easily break the rules.

to be honest.

In the field of lithography machines.

Dongyun has been blocked by the world.

As for which countries are behind the scenes, I don’t need to say too much, everyone can guess.

Anyway, I think Dongyun manufacturing can’t make it. If you want to buy it, you can’t buy it. There is no opportunity to connect and touch. It is impossible to learn from it.

nature!

So many years have passed.

Progress is boundless.

So many people have called for abandoning this field and no longer studying lithography machines, so as not to waste time, energy and money.

Understandable.

After all, the lithography machine is made from the expertise of many developed countries, and there are countless manpower, material resources and money involved.

But Dongyun wanted to make it by himself without any foundation and being blocked.

this……

Comparable to Shu Road, it is difficult to climb to the blue sky.

It is precisely because of this.

Dongyun was constrained everywhere with the chip.

For example, Yunwei is the company, and it is clear that the chip can be designed by itself, but it cannot be manufactured by itself.

Instead, they can only obediently take the designed “negative film” to companies such as Taiwan Semiconductor Manufacturing Co., Ltd., and use the latter’s lithography machine to fabricate transistors and then combine them into chips.

Everyone look…

The most critical aspects of the chip are two.

One is design, and the other is manufacturing.

If you only know how to design, but can’t make it, then you will be a fart. If you are not obedient, you will be pinched. If you want to resist, you will be forced into a desperate situation. Life and death cannot be controlled by yourself. Naturally, it is miserable.

certainly!

Dongyun is not without the chance of a comeback.

That is: “If you don’t let me play on the chessboard, then Laozi will lift the chessboard and let you play a fart!”

This chessboard is not meant to start a war, but to turn the so-called lithography machine, which is priceless, into rubbish.

Because……

The manufacture of the chip does not necessarily require a lithography machine.

For example 50 years ago.

When there is no technology in China, “PN” knots are manufactured manually, and then chips are produced.

But this method has been eliminated.

At present, if you want to manufacture high-quality silicon-based chips, you must use high-end lithography machines.

But our technology is not good, but we can make breakthroughs from materials!

Silicon-based chips require high-end lithography machines, but carbon-based chips are completely unnecessary.

If carbon-based chips can be successfully developed, only ordinary lithography machines and even laser equipment are needed.

Because all the performance of carbon-based chips can be used to sling silicon-based chips, the priceless high-end lithography machines will naturally be ruthlessly eliminated, and they will all be thrown into scrap sites.

What is this called?

This is called a big reshuffle of the industry.

Let your previous efforts be put into water.

Want to block me?

What a terrible blockade.

Laozi lifted all of your chessboards and jumped directly from the third step to the fifth step to achieve a corner overtaking.

“Um!”

“This paper should be fine.”

“After all, I wrote it myself, and there is no possibility of calling it back. I just don’t know where to submit the paper?”

“Nature?”

“Scaience?”

“Or PNAS?”

“Or PhysicalReviewLetters?”

“It’s really hard to choose! I don’t know if there is any better suggestion ヾ(*ΦωΦ)ﾉ!”
