Chapter 309: Super Materials – Two-Dimensional Tin

With the passage of time, Ye Hua has strongly integrated the most cutting-edge talents of the entire semiconductor alliance to form a team-level research assistant team, and the talents of other semiconductor companies have been lent to him.

The research base is in the Zifeng Research and Innovation Center, the tasks assigned to Ye Hua by Xiang Yuansheng have also been completed, the R&D center has been established, and now the research assistant team is basically in place, and the next task is to go all out to climb science and technology.

However, Ye Hua did not put all his energy on the scientific research team, because the trouble of the coastline company is still there, and it has not disappeared, although he is not worried, but the current situation is that the crisis of the coastline has not been resolved, but is getting more and more fierce.

Especially when announcing the birth of this new semiconductor industry alliance, outsiders think that Ye Hua is going to completely turn his face with Silicon Valley and American partners.

The media at home and abroad are hyping up a series of wordings such as Yongzhen PK Silicon Valley, Huaxia Semiconductor PK American Semiconductor, turning face, full firepower, self-determination, new king ascending the throne, dynasty eternal, etc.

When the people who are engaged in eating melons see these news, it seems that the two sides are completely breaking up and want to fight each other.

However, none of this affected Ye Hua's established arrangements.

In the following time, he frequently ran back and forth between Shangdu and Zifeng Research and Innovation Center, and Ye Hua was a little stressed, after all, he was regarded as the hope of the whole village.

The allies all believe that even with Ye Hua taking the lead, even if a miracle is born in the semiconductor industry, it will take three or even five years to make a breakthrough.

After all, integrated circuits are really too complex, and the requirements of the manufacturing process are also extremely demanding, Huawei began to lay out integrated circuits 15 years ago, but it has not yet begun to bear fruit, and it is still in the case of an average of three or five billion US dollars of R&D funds thrown into it every year.

The annual revenue of other domestic semiconductor companies is less than half of that of Huawei HiSilicon's R&D investment in semiconductors, and some semiconductor companies are even among the top in China, but their revenue is only three or four billion yuan.

It can be seen how difficult it is to break through the level of semiconductors.

But Ye Hua's ambition is so big that all his allies can't dream of, because his expectation in his heart is that he will not only make a breakthrough in about half a year, but also be able to connect to the supply of chips, that is, to be able to connect to the chip supply before PHC uses the last family foundation.

Ye Hua didn't tell them the goal he set, because his goal was too exaggerated, and saying it would make the partners think that you were unreliable, after all, you want to do it in half a year, what is the difference between this and opening a hang......

……

The source of basic materials for integrated circuit devices in the world today is the application of silicon, but Ye Hua gave up the application of silicon and chose a new super material - tin.

Two-dimensional sterene, to be exact.

The superconductivity of tin has been discovered for more than a hundred years, but this phenomenon is only found in white tin (β-Sn).

Another common phase of tin is gray tin (α-Sn), which is semi-metal and does not possess superconductivity.

It is only in recent years that people have realized that gray tin is a topological insulator.

Scholar Zhang Shousheng predicted that a single layer of gray tin, that is, two-dimensional tin in a special direction of the crystal, has a hexagonal structure similar to graphene, and may have a series of important topological properties such as the greenhouse quantum spin Hall effect.

His prophecy has not yet been confirmed, but his prophecy is right, because it corresponds to the knowledge in Ye Hua's mind, and the development he is doing is to turn his prophecy into a reality of truth.

The first thing Ye Hua did was to get the production technology of two-dimensional stylene, and now he has the top research team in China and even the world's top integrated circuit development.

There is a team for the production of two-dimensional stane, and another team is to carry out ultra-low temperature electrical and magnetic transport measurements for the tinene films.

In the entire huge research assistant team, more than sixty percent are people from friendly businessmen, and the rest are people from the coastline company, and the technical engineers of the coastline worship Ye Hua blindly, because only those who have experienced it will understand why they worship him so much.

At first, the new group of scientific research engineers from friends were very unsuitable for Ye Hua's research style, and they felt as if they were helping out.

However, Ye Hua directly gave them the data, and the conclusion, and handed them to work is to verify his conclusion through experiments, after all, any theory must withstand experimental proof or falsification before it can become the truth and be firmly believed by the world.

Otherwise, it can only be a hypothesis.

Surprisingly, they found two-dimensional superconductivity in subsequent experiments with two atomic layers and thicker films of tinene, which was the first time that superconductivity had been experimentally confirmed in gray tin.

This is an exciting breakthrough.

Subsequent experimental studies showed that the density of states of the tinene was modulated by the substrate, resulting in the emergence of superconductivity.

By changing the substrate thickness, the transition of steneene from a single-band superconductor to a double-band superconductor was also achieved, and the team was even more excited that the epitaxial growth of the steneene film was extremely stable and its superconductivity could be maintained for a long time without any protective layer.

And how long it takes time to verify, there is no way to do this, to get the actual data, you can only wait.

But Ye Hua once again gave them a surprising conclusion, and its superconductivity can be maintained for 28 months.

The researchers of the new group of friends were skeptical at first, but the previous verification made them doubt themselves as well.

In the days that followed, for the first time, they discovered that it was so easy to engage in R&D, and that so many results had been verified in such a short period of time.

It's not easy.

If it was said that when they were engaged in scientific research on their own before, it seemed that they needed to do a question step by step, but now Ye Hua gave them conclusions and then went to experiments, which is equivalent to copying the answers to you in the exam.

How could it not be easy?

Then these people gradually fell into a situation of blind worship of Ye Hua, because facts speak louder than words.

According to the laws of human science history in the past, at this point in time, it is indeed time for a scientific god-level figure like von Neumann and Dirac to appear.

The members of the research assistant team felt more and more that Ye Hua was, and he might be more terrifying than those god-level scientists in history.

Although the research assistant team was pleasantly surprised by the fact that they had obtained so many verification results in such a short period of time, compared to achieving complete autonomy and supplying to the market, this is just the beginning, if the whole goal is 100%, then the results achieved now are only 3%, which shows the difficulty of integrated circuits, Ye Hua really does not dare to boast in front of so many domestic semiconductor bigwigs.

However, everything is difficult at the beginning, for this task, the beginning is good and the back will be more and more smooth, because the upstream end is done, the research team is immediately disbanded, and then distributed, IC design is carried out IC design, packaging and testing is carried out in packaging and testing, and all links in the entire integrated circuit industrial chain are carried out at the same time.

The major companies that join the CSAC Semiconductor Industry Alliance have concluded a unique regulation, that is, only members of the system can obtain the right of priority supply, in fact, Ye Hua is following the model of the Dutch lithography company ASML.

Of course, the model is good, and Ye Hua is not a pedantic person.

ASML's stipulation is that only by investing in ASML can you get the right of priority supply, and the Chinese people are not among them, no way, because the Chinese people have the ability to "write the wheel eye", so they are all squeezing out the rabbit.

To put it simply, ASML requires his own customers to invest in themselves first, and such a special cooperation model allows ASML to obtain a large amount of funds, including Intel, Samsung, TSMC, and Hynix all have considerable shares in ASML, and it can be said that most of the world's semiconductor industry is ASML's "relatives", which are basically "related to each other", which forms a huge community of interests.

ASML uses investment means to maintain this model, but the coastline is definitely not good, because Ye Hua is the master who has both money and technology, but he lacks helpers, and he is a reliable helper.

But a living person can't be suffocated by a bird, and change makes sense, so Ye Hua chose another means to maintain it, that is, patented technical barriers.

That is, in the CSAC semiconductor club system, all the patent barriers are broken, and then the watermelon is cut and divided, and only the members of the system can have priority access to the right to supply, which also forms a huge community of interests.

Of course, with the advancement of development progress, the share of the core technology of the coastline company is expanding, and Ye Hua still has an unremitting pursuit of core technology.

However, the watermelon has been cut, and the Shoreline Company promises to take only one of the pieces, and as long as the other allies do not retreat from the group, the interests will not be harmed, at least not targeted by the Shoreline Company.

After all, your coastline is everyone's default alliance leader, or you are also Ye Huake's principal of the CSAC system.

Ye Hua naturally knows how difficult it is to gather a group, and how simple it is to break a group, for example, as long as the injustice of the principal will make a seemingly unbreakable alliance fall apart in an instant, and the problems of other participants are all minor problems, and the vacated position will be replaced immediately, but the injustice of the principal party will greatly reduce the credibility of the entire system.

And this time, CSAC was born so quickly, and the time, place, and people are indispensable.

This book is a little fresher, the author of this book, including many other scientific and technological texts, basically want to write graphene into it, it's about to rot the street, we don't play graphene in this book, let's play tinene, don't think it's nonsense, the technology that has appeared in this book so far is cutting-edge hot, and siene is the frontier project of basic materials, and it is also Zhang Shousheng's prediction, maybe the future of integrated circuits will be siren instead of silicon materials, not graphene, because the current research shows that tinene is better than graphene. )
