From all-round academic master to chief scientist

In addition to Huawei taking advantage of this trend, there are also rumors that foreign mobile phone SOC chip design companies have begun to contact Chinese chip manufacturing companies. Of course, there are not many companies that can design mobile phone SOC chips now, except for Huawei. In addition, only three companies, Qualcomm, Apple, and MediaTek, have approached China Chip Manufacturing Company. Samsung naturally manufactures its own chips for itself. Of course, its own chips do not have a strong presence in the mobile phone market. .

However, these companies are only in contact now, and are still waiting for Warwick's new mobile phone to be released to actually test its performance.

Lin Xiao said something very impressive at the press conference, but how it will actually perform in the end will have to wait until the actual results come out.

The data usually introduced in press conferences or product details pages are only laboratory data.

The experimental data obviously cannot be taken seriously. If the actual consumer experience can completely match the experimental data, then some mobile phone manufacturers will probably go bankrupt, because their experimental data will obviously be very embarrassing.

However, it will take some time before Warwick’s new mobile phone is released, so it will take some time to verify this news.

Of course, it is not only the design companies of these mobile phone chips that need Chinese chip manufacturing companies. In addition to them, there are also manufacturers of computer processors and graphics cards that are also interested.

For example, AMD got in touch early and asked if it could make processors and graphics card cores, and hoped to reach cooperation as soon as possible.

For massage parlors, although they not only compete with Intel on CPUs, but also compete with NVIDIA on graphics cards, and they seem to be competing with these two companies named Ying, their actual technology has always been dominated by these two companies. It’s pressing, which is why it’s called an agricultural enterprise.

And now that Huaxia Chip Manufacturing Company has the world's best 5nm process, the massage parlor will certainly not miss this opportunity.

Both Intel and Nvidia are very aware of the concerns of massage parlors. However, Intel has its own chip production line and has no time to do this. Nvidia's Huang Leyi is still thinking about how to use the 40 series that was recently launched. Graphics cards have pushed up the plummeting stock price, so now they have no intention to study the possibility of finding Huaxia Chip Manufacturing Company to produce their graphics cards, so they can only watch the massage parlor take advantage of the opportunity.

All in all, in addition to the mobile phone industry, the PC industry is also in turmoil. These companies are also the most famous in the entire semiconductor industry, and they are also the most profitable companies. Their movements can be said to have made China Chip Manufacturing Company a media public opinion A frequent visitor to the Internet, the world is paying close attention to what this Chinese company will do next.

However, Huaxia Chip Manufacturing Company is obviously not in a hurry for these things. After all, the production capacity brought by five X-ray lithography machines is still relatively limited. At least it must wait until a few more production lines are built.

In addition, the emergence of Huaxia Chip Manufacturing Company is obviously good news for China’s supercomputing industry.

Although Huaguo Supercomputing is very strong, due to the upper limit of chips in the past, it is no longer possible to maintain the number one position of a single machine.

For example, the Sunway TaihuLight uses the domestic processor Sunway 26010, which uses 28nm process technology. The number of processors in the Sunway TaihuLight is as high as 40,960, and each processor has 260 cores. This is equivalent to a total of more than 10.64 million cores in Sunway TaihuLight.

The supercomputers ranked ahead of the Sunway TaihuLight, such as the American Summit supercomputer, use the core of the 14nm process and have only more than two million cores, but their computing power is about 1.7 times that of the Sunway TaihuLight. Or so, this is because of the advantages of the manufacturing process.

In the past, China had no way to deal with this situation. Although it had world-class supercomputer construction capabilities, it could not produce chips with advanced processes. Intel was even banned from providing processors to China's supercomputers.

But now that China has its own top-notch chip production capabilities, it is naturally able to start trying to design such top-notch chips.

It is reported that domestic scientists studying supercomputers have already made such plans.

But if you really want to build it, funding will obviously be a big problem. After all, the production cost of 5nm chips is inherently much higher than that of 28nm process chips.

Therefore, this matter is still under planning and discussion, and there is no plan to build it yet.

However, no matter what, being able to start discussing this matter is much better than having no discussion at all before.

In the past, even if you had money, you couldn't get it, but now it's just a matter of money. So people are more confident than before when they talk in daily life, and they also have enough confidence when confronting those who hate Guo Party online. confidence.

China has developed an X-ray lithography machine that even foreigners cannot develop, and it is produced independently by them. This makes them have no confidence.

Undoubtedly, the complete success of the X-ray project has begun to subtly change people's mentality.

…

Time passed slowly and it came to the beginning of December.

It’s naturally quite cold in Beijing in December.

Of course, this coldness cannot stop Lin Xiao in Dingguang Research Institute from feeling excited.

"Finally done."

He picked up a black and elongated solid on the table in front of him and looked at it carefully. This thing was yttrium barium copper oxide, the world's first high-temperature superconductor discovered.

However, unlike the yttrium barium copper oxide that is usually prepared, the yttrium barium copper oxide in his hand has another molecular structure.

"Is this the thing that has kept you doing it for more than a month?"

A person came over and asked with a puzzled look on his face.

This person is Chen Xun, a domestic master who studies superconductors that Lin Xiao successfully recruited from the Superconducting Laboratory of the Institute of Physics.

Of course, strictly speaking, Chen Xun does not belong entirely to the Institute of Physics. He just works in the Superconducting Laboratory of the Institute of Physics. He is still a professor at the School of Physics of Beijing University.

Because the Superconducting Laboratory of the Institute of Physics is currently the largest superconducting laboratory in China, people from other institutions can also join as researchers and share the laboratory.

Of course, this present situation is about to become a thing of the past, because the superconducting laboratory that is about to be successfully built by the Dingguang Institute will take its place.

This is why Chen Xun was easily recruited by Lin Xiao. In addition to the name of Dingguang Research Institute, a larger superconducting laboratory is very attractive to superconducting physicists like him.

After hearing Chen Xun's words, Lin Xiao smiled and nodded: "Yes, that's it."

"An equivalent topological body found based on the electron topological bonding theory? In that case, didn't you explain in the electron topological bonding theory that their properties are the same?"

Lin Xiao shook his head, "The properties are the same, but the internal structure has changed after all, so in some cases, they will produce different effects."

"What effect? ​​Superconducting?"

Lin Xiao smiled and said, "Let's try it first."

Then he came to the side, brought over a cylinder filled with liquid nitrogen, and then opened the bottle.

A stream of white gas emerged from the mouth of the bottle. This white gas was naturally water mist. The low temperature of the liquid nitrogen inside caused the water molecules in the air to condense into small water droplets, thus forming this phenomenon.

Of course, there is nothing strange about this. Lin Xiao directly put the new structure of yttrium barium copper oxygen in his hand, clamped it with tweezers, let it be completely immersed, and began to cool.

When the time was almost up, he took it out, quickly wrapped it in a layer of insulator, and then placed it on a shelf on the experimental bench. Then he took the alligator clips and clamped it. both sides.

Next, start energizing the alligator clips.

Although the current cannot be seen with the naked eye, it is obvious that the yttrium barium copper oxygen in front of me is already charged with electricity.

Then, Lin Xiao randomly found a small magnet from the side and placed it on it. Suddenly, the small magnet floated "magically".

Obviously, this is the Meissner effect of superconductors. Due to the current flowing through YBCO, the YBCO that has entered the superconducting state has complete diamagnetism, which makes the small magnet float.

However, these are normal. Chen Xun next to him has done this experiment countless times. For now, Lin Xiao has done nothing that should surprise him.

But as soon as he thought this, Lin Xiao started to move.

Because he began to increase the input current.

Seeing this scene, Chen Xun couldn't help but be stunned, "Director Lin, what are you doing?"

If you continue to increase the current, according to YBCO's critical current density of 5*10^8A/m, once it exceeds, it will immediately exit the superconducting state and return to normal. At that time, its internal temperature will also rise sharply due to the current thermal effect. If it rises, it will have to be refrozen at that time.

The cross-sectional area of ​​Lin Xiao's YBCO is estimated to be only 0.5 square centimeters, which means that its maximum current can only be 25,000 amperes.

And now the current input by Lin Xiao has reached as high as 22,000 amps!

But that's not all, Lin Xiao is still rising.

Even more than 25,000 amps!

However, what Chen Xun couldn't believe was that even though the current exceeded 25,000 amps, the YBCO still remained in a superconducting state!

In fact, the current size is approaching 3WA!

"this……"

Chen Xun couldn't believe it. Could it be that he had seen it wrong?

The cross-sectional area of ​​this thing is more than 0.5 square centimeters?

But he couldn't believe it at all, because he could tell at a glance that the cross-sectional area of ​​this thing was definitely not more than 0.6 square centimeters!

"Director Lin, why is this?"

Finally, he couldn't help but ask.

Lin Xiao replied calmly: "Because its critical current density has increased."

Chen Xun was startled and recalled what Lin Xiao had just said to him.

The internal structure of this YBCO is different, so in some cases, it will show different effects...

At this time, he already understood what Lin Xiao meant!
