Chapter 396 The Gap

Watching ASML's live broadcast, apart from some mentality of watching a movie, most people are concerned about the performance of the chip in the future.

graphics card, cpu, games, etc.

But this kind of picture still arouses a more heavy feeling in China.

Isn't what Umbrella is facing a microcosm to some extent?

Under the current order established by Dali, all developed countries are beneficiary groups.

In this case, even if Damei often regularly harvests the world according to its own domestic conflicts, inflation and various economic problems, and cuts their flesh to fill itself, all parties still have a certain degree of tolerance for Damei, and accept Damei Nice dominance!

Who wants to be an enemy of Damei?

No.

But sometimes it's not enough for you not to think about it, you have to have the same thoughts on the other side.

If you fall behind, you will not necessarily be beaten, but if you fall behind and have money, you will definitely.

"Mad, what's the matter with the sudden pressure? Isn't it aimed at Umbrella?"

"Hey, it seems that we may face in the future..."

"I'm so angry for no reason."

"Only we will feel angry, because other people don't care anymore, and there are even some who are proud of being stationed in the army."

"Isn't that how we came here before? In fact, the world has never been peaceful, but we live in a peaceful country and era."

"Now, they want to come back again. What Umbrella is facing is probably what we also need to face. We are not living in a peaceful era..."

"Of the 190 countries in the UN General Assembly, only three have not been involved in military intervention by Damei. This is because these three countries are too small to be of value."

"Then why should we make them angry?"

"Because you're not white, they can't even manage their own dog, so why would they care about your life or death? Of course, some people think it might be different if they lick it early..."

"Isn't it popular over there that you run first and look down on later run?"

"..."

It can be said that ASML's sudden arrival to put extreme pressure on Umbrella has actually brought a huge pressure to the country.

Even when the DUV lithography machine was still tackling key problems, it suddenly came up with this brand new track, which brings together all the world's top-notch EUV lithography machines. It is said that the lithography machine can reach the limit of silicon-based chips. A huge pressure.

At the same time, many people also turned their attention to Umbrella.

I don't know how this miracle-making company should face...

At the beginning, Umbrella took out the DUV lithography machine for the first time, and now there are indeed many people to see if they can also take out the EUV, but the team lineup of ASML has already been laid out before.

Umbrella does have the advantage of 'magic power', but he has always paid attention to the basic rules, so they feel that they cannot be conquered!

Maybe some of the difficulties inside can be overcome, but overall I'm afraid it really won't work!

There are also many people on the Internet who pay attention to this matter.

But for them, they obviously don't have so many thoughts, and they are more concerned about the impact on themselves, and whether Umbrella will not be able to keep up after being sanctioned!

"What will happen to the chip of the Red Queen's bracelet in the future?"

"Sanctions for what? Who is hindering them from building a city on the sea?"

"It's such a lame excuse again, can you change it, I'm tired of hearing it."

"The latest chip hasn't come out yet, but it is estimated that the chip factory will make an official announcement soon. I don't know when the fab will start construction."

"I have friends in this industry, and they say that EDA is very fast after Umbrella's upgrade."

"No way, the EDA software is upgraded by others, and the sanctions are reversed?"

"Hey, maybe the Red Queen's phone won't work in the future, the ten-fold gap is too big."

"Playing console games on mobile phones is just around the corner."

"I still want to see what will appear when the upgrade collides with the 'Red Queen+'."

"A certain song should also have artificial intelligence, right? With this kind of blessing, it can't be compared to the Red Queen."

"I hope Umbrella can license the holographic technology..."

"..."

...

When Asmail made a strong attack and there was a lot of discussion outside.

Wang Yi was dull-headed adjusting the materials in front of him.

When he first started working on superconducting materials, Wang Yi subconsciously chose the silver factor, and finally chose the silver-copper alloy.

In the end, by relying on brute force, it was true that a small piece of room temperature superconductivity was produced, but Wang Yi was exhausted enough.

If this kind of superconducting material is to be used in the future, it will not be enough for him to masturbate 24 hours a day without doing anything.

So it was thrown aside.

But this time, Wang Yi carefully interpreted the hydrogen sulfide experiment.

What is superconductivity?

No resistance plus diamagnetism, both are indispensable.

Of course, this non-resistance itself is relative, but it has no effect. When the resistance is less than 10^-25 ohms, it can be regarded as non-resistance.

The first superconductor discovered was mercury.

Later, many materials that can achieve superconducting properties under the cooling of liquid helium were slowly discovered.

Take metal as an example. Metal is a metal lattice structure composed of metal atoms, and free electrons can move freely in it, so it can conduct electricity.

However, the metal atoms themselves are also in a vibrating state in the crystal lattice, and will "collide" with the moving electrons to absorb part of the energy and convert it into its own internal energy, which is reflected in the temperature rise after electrification.

Usually, as the temperature rises, the speed of metal atoms becomes faster and faster, and the possibility of colliding electrons will also increase, so the resistance will usually increase.

This is also the reason why the mercury resistance was tested at low temperature in the first place, to see how small the resistance can be.

But the birth of superconductivity is not purely because the temperature is too low to make atomic vibrations smaller, which can only be regarded as one of the reasons.

When the electrons are moving, there is a probability that the metal atoms will collide no matter how low the movement is.

The superconducting material itself is not absolute zero, and it does not prevent the vibration of metal atoms.

Therefore, the reason for the birth of superconductivity needs to continue to be distinguished from the two types of elementary particles, bosons and fermions.

Fermions are semi-odd particles whose spin is 1/2 or 3/2. They follow the Pauli exclusion principle, that is, a quantum state can only accommodate one particle, and they cannot overlap and superimpose together. We can touch Matter, in a sense, is composed of fermions.

A boson is a particle with an integer spin, which does not follow the Pauli exclusion principle, such as a photon. Taking an actual point as an example, it can be regarded as a magnifying glass that can compress sunlight into a small point. All photons can theoretically superimposed in a quantum state.

As for the electrons as fermions, the thicker the wire, the better for the current to pass through.

What we usually call the singularity at the center of the black hole, and the singularity at the time of the Big Bang, is that the degeneracy pressure between fermions is destroyed by a greater force, and they collapse into a quantum state, forming a magnifying glass that gathers sunlight Similar effects, infinite stacking.

After understanding this, it is necessary to extend another kind of substance, which is called superfluid, which is that in a specific environment, two kinds of fermions are coupled with each other to form a Cooper pair, and the original semi-odd spin coupling becomes an integer, thus obtaining a boson-like characteristic.

Like helium nuclei.

This allows superfluids to make friction disappear, in the form of being able to flow quickly through extremely thin tubes without sticking, or to rotate around a ring with a little force and almost forever.

The superconductivity in the low temperature state is also based on this reason. The energy of the electrons as fermions is lower than the energy of the Fermi-Dirac distribution, which leads to the coupling of two pairs to form a Cooper pair, and then freely in the conductor. 'flow' is not affected.

So how to combine electrons with Cooper pairs is the key.

The reason why hydrogen sulfide was chosen in the paper is because 'hydrogen' is the lightest nucleus. When electrons move in the conductor, it can attract nearby atomic nuclei to move. Similarly, when the atomic nuclei move densely, they will attract The next electron makes it easier to pair and complete the match.

This can reduce the conditions required for electrons to combine into Cooper pairs, without the kind of temperature close to absolute zero.

As far as the laboratory results are concerned, the direction is not wrong.

It is to try every means to reflect the metallic nature of hydrogen. Yes, hydrogen can form "metallic hydrogen" under extreme conditions, but human technology is still unable to do so, so diamond pressurization is used to reduce the temperature. The material hydrogen sulfide was chosen to achieve some of the properties.

Wang Yi also entered into a misunderstanding before, always thinking about using the properties of metal and silver to form a superconducting alloy.

However, using silver's intervention in the magic power to stimulate the metallic nature of hydrogen seems to be much simpler than silver-copper alloys!

Silver hydride, this is a strange thing that Wang Yixin tinkered with.

Although he still needs to mobilize the magic power of the mage tower to make it himself.

But the difficulty is much more convenient than the previous silver-copper alloy, and the efficiency is much higher.

After the completion of the Mage Tower in Penglai, although the production capacity is not large, it should be self-sufficient.

And even though the big guys can't do it now, it's not a big problem to just make some chips and help Lin Shiqin upgrade a little bit.

Anyway, the EUV lithography machine knocked out by myself is solid, and I can directly work on this material even if I am alive...
