Hand rubbing nuclear fusion live in the wilderness

Chapter 286 The layout of Huaguo
After learning through the barrage that domestic manufacturers were directly fighting with the island country, Won didn't say much, but turned around and continued to complete the preparation of monocrystalline silicon.

However, attentive viewers and experts from various countries found that the anchor's explanation seemed to be quite detailed.

"'Chemical Vapor Deposition-Silicon Core Epitaxy' is generally the most important way to prepare single crystal silicon in two ways."

"The first is the 'hydrogen reduction of silicon tetrachloride'."

"Friends who have seen me prepare silicon carbide crystals before should know that the 'hydrogen reduction method of silicon tetrachloride' is a method for preparing high-purity polysilicon."

"But in fact it can also be used to make single crystal silicon."

"However, what I use today is not this, but the second 'silane thermal decomposition method'."

"Compared with the 'silane tetrachloride hydrogen reduction method', the 'silane thermal decomposition method' is simpler, and the preparation process has fewer steps."

"But there is one thing to be aware of."

"That's the temperature."

"Temperature has little effect on the epitaxial growth rate of silane, but has a great influence on the quality of the epitaxial layer."

"For example, when the temperature is higher than 1100°C, the self-doping effect of the epitaxial layer is more serious. On the contrary, if the temperature is too low, the crystal integrity of the epitaxial layer is poor and there are many defects."

"Practice has proved that when hydrogen is used as a carrier gas, about 1050 ° C is the optimum growth temperature; the most important factor affecting the growth rate of silane epitaxial growth is the concentration of silane in hydrogen, generally with the increase of silane in hydrogen, the growth rate also increases. proportionally increased."

"It should also be noted that although silane thermal decomposition epitaxy has the advantages of low growth temperature, simple reaction mechanism, no halides, and no self-doping."

"However, silane is flammable and explosive, and the single crystal silicon produced during silane epitaxy is greatly affected by the purity of silane gas, and the distribution of impurities in the epitaxial layer is also difficult to control."

"So how to extract high-purity silane gas and keep the equipment clean and clean is the focus of using the 'silane thermal decomposition method' to prepare single crystal silicon."

"."

Through Won's continuous explanation, other viewers in the live broadcast room gradually found that the explanation content seemed to become more detailed under the prompts of some attentive viewers.

Details such as temperature control, which is specific to a certain point, and the growth rate increases with the increase in the concentration of hydrogen gas, were absolutely absent in the previous live broadcast.

And this time there is.

This excited most of the viewers in the live broadcast room. There were three friends and five friends. These viewers kept calling their friends to come and watch in reality.

Even though they couldn't understand, or even understand what Han Yuan was talking about, the number of viewers in the live broadcast room was still increasing rapidly.

['Three six' give away grilled fish*999, the anchor is awesome!The details are in place! 】

[Come here, my favorite part is here. 】

[Can the anchor explain in more detail?Although I have only attended elementary school, I am addicted to knowledge and cannot extricate myself from the ocean. 】

【I just went to kindergarten and I was taking notes in my little notebook! 】

['The most indispensable thing in the country is my kind of garbage' send out the plane*1, Xiongqi! 】

['Sister Zhou can still rush if she doesn't speak' to send a super rocket * 100, I will reward Sister Zhou to shut up, and I will reward the anchor to speak! 】

[I'll wipe it, sister Zhou, can you rush down too? 】

[? ? ?Sister Zhou who doesn’t speak is still very good, although the airport is a bit flat (ov)ノ]

【Book Title: "My Dumb Bride"; Chapter 1: My Dumb Bride; Chapter 2: The Miracle Doctor Comes; Chapter 3: My Wife Speaks; Chapter 4: We Divorced (End)]

[Upstairs is a masterpiece, hurry up and write, I will go to your room to 'arch' you to death if I don't see this book at the starting point in three hours! 】

[Sister Zhou is such a beautiful girl, she must speak very nicely ()]

[It's crooked, the topic is crooked, didn't you tell the anchor to give more details?Sister Zhou went to discuss everything. 】

【So what do you choose? 】

[I choose Miss Zhou (dog head)]

The live broadcast room was extremely lively, but the speed of the audience changing topics was still so fast.

Han Yuan glanced at the barrage while explaining.

He still knows sister Zhou, who is also well-known on Douyu platform.

As a "loyal" user of Douyu platform, how could he not know the famous "dumb sister Zhou".

This is a 'sister' who is full of royal sister's flavor when she doesn't speak, and a manly 'girl' who speaks.

Coupled with the stalk that Lu Chao would not care about, Sister Zhou is quite famous.

Ignoring the barrage, Han Yuan focused on the work at hand.

At the same time, in reality, in Huaguo, the "Major Science and Technology Task Bureau" of the Chinese Academy of Sciences and the "Metallurgical and Materials Engineering Department Office" of the Chinese Academy of Engineering in the capital held a press conference at [-] o'clock in the evening.

This kind of temporary press conference held during off-duty time has attracted the attention of many people and many countries.

Especially today, there are many company manufacturers and the island country's single crystal furnace and monocrystalline silicon suppliers.

Many people had speculated about this matter before, but now that the Chinese Academy of Sciences has stood up, it is even more exciting.

Has the Chinese Academy of Sciences been able to produce high-purity monocrystalline silicon in batches?

Or did the Chinese Academy of Sciences contact the anchor?Obtained the preparation technology of monocrystalline silicon from him?
If there is the support of this anchor, then the top-level lithography machine, carbon-based chip, laser weapon, etc., etc., were revealed during the live broadcast.

Do these things also exist?

Or think a little deeper, is it nuclear fusion, sub-light speed flight and other technologies?

Is it already there?

Can't help but think otherwise.

After all, time is of the essence.

Many companies in Huaguo have to pay liquidated damages to terminate the contract with the island nation's monocrystalline silicon furnace supplier.

And just at this time, everyone was surprised by this decision, and there were a lot of discussions.

The Chinese Academy of Sciences in Huaguo stepped forward and chose to hold a press conference during non-working hours.

Who dares to say that there is no connection between the two?
Even if there is no relevant connection, it is definitely extremely important news for the Chinese Academy of Sciences to come out at this time. Otherwise, with Hua's restrained character, it would be impossible to make such a publicity move.

Beijing time, it was close to eight o'clock in the evening.

In a spacious and bright venue, the media personnel of the Chinese Academy of Sciences, who are responsible for the announcement to the outside world, are busy.

In the venue, countless reporters had already squatted in their positions with their own eating fellows.

At eight o'clock, a press conference was held.

Relevant persons in charge of the Bureau of Major Science and Technology Tasks of the Chinese Academy of Sciences and representatives of scientific research and management personnel from the National Science Center and other units came to the stage on time.

Looking at the dense crowd below, the person in charge of the press conference spoke.

"Ladies and gentlemen, good evening, and welcome to the press conference of the Information Office of the Chinese Academy of Sciences."

"We are very honored to invite academician Bai Chunli of the Chinese Academy of Sciences to introduce the content of this press conference. We welcome you all."

The camera moved, and a middle-aged man with glasses stood up and gave a slight gesture, and a series of news came out of his mouth.

"."

After a series of daily speeches, Academician Bai cut to the key points of this press conference:

"A few days ago, under the leadership of the National Laboratory of the Chinese Academy of Sciences, with the assistance of the Department of Chemistry, the Department of Technical Sciences and the Academy of Engineering of the Chinese Academy of Sciences, the National Laboratory in Beijing has mastered the smelting and preparation technology of high-purity single crystal silicon."

"Its preparation technology has been quite perfect, which can realize automatic mass production, and the purity of single crystal silicon prepared by smelting is as high as 99.999999%."

"."

At nine o'clock, the press conference ends.

When the meeting ended, the reporters in the venue left quickly, wanting to rush to edit and release the manuscript as soon as possible.

Although the meeting was short and there was only one piece of content for the press conference, the amount of information was extremely explosive.

[Congratulations to the Chinese Academy of Sciences for mastering the smelting technology of monocrystalline silicon with a purity of 99.99999% or more! 】

【Shock!Huaguo manufacturers are angry with island country lithography machine manufacturers, and this is the reason for the breakup between the two. 】

[One step closer to the lithography machine! 】

All kinds of news and information soon flew all over the sky.

In less than an hour, relevant information occupied the entire Internet and rushed to the top of the list.

And around ten o'clock, most of the melon-eating people in the country were basically still awake, and they ate this freshly baked big melon in the first time.

[Awesome!The Chinese Academy of Sciences is awesome!Huaguo is awesome! 】

[It's amazing, I said why those domestic manufacturers are so courageous, it turns out that the country is behind it. 】

[It's late at night, laughing and making a goose cry, this time the little devil is really going to be unlucky. 】

[Tell me, is there any support from the anchor behind this? 】

[There must be! 】

[I don't think so. The Chinese Academy of Sciences didn't mention the anchor at all at the press conference, okay?It is about our country's own efforts. 】

[Just such a coincidence?There has been no breakthrough in the preparation of monocrystalline silicon for so many years. Will this be a breakthrough? 】

[Don't think about it, even if there is an anchor behind it, the country won't say it. Could it be possible to tell the world clearly that we have found this anchor? 】

[I don't think so. If there is this anchor's support, why does this anchor still talk about it in such detail during the live broadcast? 】

[I think this is also strange. If there are various materials to support it, I will definitely not talk about it in such detail later. 】

[Can't it be developed by our country itself?The Chinese Academy of Sciences has said that it is the joint efforts of scientists in our country! 】

[What are you talking about, just ask the anchor. 】

Soon, hot searches on Weibo, Tieba and other places were transferred to Won's live broadcast room.

It's a pity that Han Yuan didn't answer this question at all, even though he saw it, he didn't answer it.

Like the melon-eating audience at Huaguo University at night, the minds of all countries are actually the same.

"Is there any involvement of that anchor behind this incident? Has Huaguo gained the support of that person?"

Won was a little surprised by the announcement that the Chinese Academy of Sciences has been able to produce high-purity single crystal silicon by itself.

The preparation of single crystal silicon is not difficult, but the difficulty is to improve the purity.

The purity requirements of monocrystalline silicon used in top-level silicon-based chips are beyond what ordinary people can imagine.

Monocrystalline silicon with a purity of 99.999999% or more, what a concept.

It is equivalent to only 0.001 grams of impurities in one kilogram.

This purity index is really beyond the reach of ordinary countries.

However, South Korean Won is very clear that he has not provided any scientific and technological information to anyone in any country in private messages before.

In other words, the information announced by the Chinese Academy of Sciences this time was indeed developed by Hua Guo himself, and may even have been conducting research in this area a long time ago.

After all, compared with photolithography machines, the preparation of single crystal silicon is much simpler.

Moreover, in a sense, monocrystalline silicon is even more important than lithography machines.

Because monocrystalline silicon has a wide range of uses, except for the most important chips.

Monocrystalline silicon is used in the preparation of various industrial electrical appliances such as solar panels for photovoltaic power generation, diode levels, rectifier device levels, and circuit levels.

The country imports tens of billions of monocrystalline silicon materials every year. If this money can be converted into domestic sales, it is indeed worth studying by the Chinese Academy of Sciences.

Especially the monocrystalline silicon material needed for photovoltaic power generation.

The South Korean won knows that the country is currently carrying out carbon-neutral actions, and it is a national order to reduce the emission targets of carbon dioxide and other gases.

Thermal power generation is a very polluting environment, but thermal power generation accounts for more than 70.00% of China's current power supply.

In the past, even in order to control carbon neutral emissions, there was a phenomenon that power plants stopped and power outages occurred in residential areas.

Although photovoltaic power generation is eco-friendly and environmentally friendly, it needs to occupy a large area. Compared with photovoltaic power generation, thermal power plants and the like, the land area is a drop in the bucket.

However, there is no shortage of land in Huaguo. The northwest region is sparsely populated and has a long sunshine time, which is extremely suitable for building photovoltaic power plants.

Coupled with the high-energy-storage lithium-sulfur batteries prepared during the previous live broadcast, it probably made Huaguo executives decide to vigorously promote new energy sources and remove oil from the attributes of fuel.

Of course, the above-mentioned things are Won's own guesses.

The lithium-sulfur battery technology he broadcast live before has given electric vehicles an advantage over fuel vehicles in terms of cruising range.

And this advantage is not limited to 01:30.

A car, with full fuel, can run only about five or six hundred kilometers.

The advantage is that there are gas stations everywhere and the extremely fast replenishment speed.

Before lithium-sulfur batteries came out, although Huaguo was also vigorously promoting new energy vehicles, the annual subsidies started at hundreds of billions.

But in fact the effect is not much.

After so many years of development, the proportion of sales of new energy vehicles has not exceeded [-]%.

However, after lithium-sulfur batteries come out, the cruising range of new energy vehicles can reach several thousand kilometers.

Although it is still far from the top battery in his mind.

But with this cruising range, most people will probably choose new energy vehicles.

It can be used for a month or two on a single charge, which is not too convenient.
