Vol 2 Chapter 309: : Super Materials-2D Tin

? Over time, Ye Hua powerfully integrated the most cutting-edge talents in the entire semiconductor alliance to form a team of research assistants. The talents of other semiconductor companies were lent to him.
The research base is located at the Zifeng Research and Innovation Center. The tasks of explaining Yuan Sheng to Ye Hua have been completed. The research and development center has been established. Now the research team is basically in place. The next task is to fully strive for technology.
However, Ye Hua did not devote all his energy to the scientific research team, because the troubles of the coastline company are still there and have not disappeared. Although he is not worried, the current situation is that the crisis moment of the coastline has not been lifted, but Increasingly fierce.
Especially in announcing the birth of this brand new semiconductor industry alliance, outsiders see in the eyes that Ye Hua is going to completely turn his face with Silicon Valley and US partners.
The media at home and abroad are a series of expressions such as Yongzheng PK Silicon Valley, Huaxia Semiconductor PK U.S. Semiconductor, turning their face, full firepower, uncontrollable power, new king ascended the throne, dynasty Yonggu and so on.
People who eat melons see these news, as if the two sides are completely in trouble, and they want to die each other.
None of this affected Ye Hua's established arrangements.
The next time, he frequently ran back and forth between Shangdu and Zifeng Research and Innovation Center. Ye Hua was a bit stressed, after all, it was regarded as the hope of the whole village.
Allies believe that even if Ye Hua takes the lead, even if the semiconductor industry is a miracle, it will take three years, or even five years, to make a breakthrough.
After all, integrated circuits are really too complicated, and the process requirements are extremely demanding. Huawei started to lay out integrated circuits 15 years ago, but it has not achieved results until now. That ’s still an average of 35 billion yuan each year. Burning out of research and development dollars in dollars.
The annual revenue of other domestic semiconductor companies is less than half of Huawei Hisilicon's investment in semiconductor research and development, and even some semiconductor companies are top in the country but their revenue is only 3 billion to 4 billion yuan.
It can be seen how difficult it is to break through the semiconductor level.
However, Ye Hua's attempt is so great that all of his allies dare not think about it, because he expects that in about half a year, not only will he achieve a breakthrough, but he will also be able to connect to supply the market, that is, after using the PHC Before the last home, you can connect to the chip supply.
Ye Hua didn't tell them the goal they set because his goal is too exaggerated. Saying it will make your partners feel that you are not reliable. After all, you want to get it in half a year. What is the difference from opening?
...
The basic material source of 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.
To be precise, it is a two-dimensional tinene material.
The superconductivity of tin has been discovered for more than a century, but this phenomenon exists only in white tin (β-Sn).
Another common phase of tin is gray tin (α-Sn), which is a semi-metal and does not have superconductivity.
In recent years, people have realized that gray tin is a topological insulator.
Scholar Zhang Shousheng had predicted that a single layer of gray tin along a particular direction of the crystal, that is, two-dimensional tinene has a hexagonal structure similar to graphene, and may have a series of important greenhouse quantum spin Hall effects. Topological properties.
His prediction has not been confirmed, but his prediction is correct, because it corresponds to the knowledge in Ye Hua's mind, and the development he is doing is to turn his prediction into a realistic truth.
The first big thing Ye Hua did was to get the production technology of two-dimensional tinene. His Majesty now has the top domestic and even the world's top research and development team for integrated circuits. He wants to achieve this by anyone within six months. People will think that the crazy goal that cannot be achieved must be developed in parallel at the same time.
There are a number of teams for the production of 2D tinene, and another team is developing the extremely low-temperature electrical and magnetic transport measurement of tinene thin films.
In the entire huge research team, more than six Chengdu people are from friends, and the rest are the people from the coastline company. The worship of Ye Hua by the technical engineers of the coastline is blind, because only after experience will they understand why Worship him so.
At first, the new batch of friends' scientific research engineers were very uncomfortable with Ye Hua's research style. It felt as if they were helping him. Everyone was ambitious, and even hoped to be able to focus on the research of a subject. .
However, Ye Hua gave them the data directly, and concluded that giving them work is to verify his conclusion through experiments. After all, any theory must stand the experimental proof or falsification to become the truth and be firmly believed by the world.
Otherwise, it can only be a hypothesis.
Surprisingly, in subsequent experiments, they found that a two-layer atomic layer and a thicker tinene film had two-dimensional superconductivity, which was the first experiment to find superconductivity in gray tin.
This is an exciting breakthrough.
Subsequent experimental studies show that the density of states of tinene is modulated by the substrate, leading to the emergence of superconductivity.
By changing the thickness of the substrate, the transformation of tinene from a single-band superconductor to a dual-band superconductor was also achieved. What was more exciting to the team was that the epitaxially grown tinene film was extremely stable and its superconductivity without any protective layer Can last long.
How long it takes to verify the specific time, there is no way to get actual data, you can only wait.
But Ye Hua once again gave them an amazing conclusion that their superconductivity can be maintained for 28 months.
The newly-joined batch of scientific researchers from the business community were skeptical at first, but the previous verification made them doubtful about themselves.
In the following days, for the first time, they found that it was so easy to do research and development, and so many results have been verified in such a short period of time.
It's not easy to see the ghost.
If they used to do research on their own before, it seemed like they needed to take a step by step to do a question, but now Ye Hua gave them the conclusion and then experimented. This is equivalent to the reason that the exam gives you the answer.
How can it not be easy?
Then this group of people gradually fell into a state of blind worship of Ye Hua, because facts speak louder than words.
According to the laws of human science and history in the past, at this moment in time, it is indeed time for the appearance of a scientific god-like figure like Feng Neumann and Dirac.
The members of the research team increasingly feel that Ye Hua is it, and it may be more scary than the great god-level scientists in history.
Although the research assistants were pleasantly surprised that they have obtained so many verification results in such a short period of time, compared to the realization of complete autonomy and supply to the market, this has just begun. If the entire goal is 100%, then it is now achieved The result is only 3%, which shows the difficulty of integrated circuits. If Ye Hua is not open, he would not dare to swear in front of so many semiconductor giants in China.
However, everything is difficult at the beginning. For this conquering task, the beginning will be smoother and smoother, because the upstream end is solved, the research team is dissolved immediately, and then distributed. IC design is engaged in IC design, packaging and testing. For packaging and testing, all links in the entire integrated circuit industry chain are performed simultaneously.
The major companies joining the CSAC Semiconductor Industry Alliance have concluded a unique rule that only members of the system can obtain priority supply rights. In fact, Ye Hua has imitated the Dutch lithography company Esmoore ( ASML).
Of course, people have to borrow a good model, Ye Hua is not a pedantic person.
The ASML stipulation is that only the investment in ASML can obtain priority supply rights. Huaxia people are not included in this list. There is no way. Huaxia people are crowded out of rabbits because they have the ability to write round eyes.
In short, ASML requires his own customers to invest in himself first. This special cooperation model has enabled ASML to obtain a large amount of funds, including Intel, Samsung, TSMC, and Hynix all have considerable shares in ASML. It can be said that the world More than half of the semiconductor industry are "relatives" of ASML, and they are basically "associated with each other", which has formed a huge community of interests.
ASML uses investment to maintain this model, but the coastline is definitely not working, because Ye Hua is a master with both money and technology, but he lacks helpers and is a reliable helper.
But living people can't be strangled by birds, and change makes sense, so Ye Hua chose another method to maintain, that is, patented technical barriers.
That is: in the CSAC semiconductor club system, all patent barriers are opened, and then watermelons are cut and divided, and only members in the system can obtain supply rights preferentially, thereby forming a huge community of interests.
Of course, with the advancement of the development, the share of the core technology of the coastline company is expanding, and Ye Hua still has unremitting pursuit of the core technology.
However, the watermelon has been cut, and the coastline company promised to take only one piece. As long as the other allies did not retreat, their interests would not be harmed, or at least not targeted by the coastline company.
After all, your coastline is the default leader of everyone ~ EbookFREE.me ~ or you Ye Hua is the principal of the CSAC system.
Ye Hua naturally knows how difficult it is to gather a group, and how easy it is to break up a group. For example, as long as the principal's injustice, a seemingly unbreakable alliance will fall apart instantly. Other participants have problems. Minor problems. Someone will immediately replace the kicked-out position, but the injustice of the subject will greatly reduce the credibility of the entire system.
And this time to be able to gather sand to form a tower so quickly, CSAC was born in this way.

(Ps: Please recommend tickets, monthly tickets, collections, and thank you for your reward.
This book is a bit fresh and refined. The author's book, including many other scientific and technological articles, basically needs to write graphene into it. It's almost rotten on the street. We don't play graphene in this book. Let's play tinene. I think it's nonsense. The technologies that have appeared in this book so far are all cutting-edge and hot, and tinene is a cutting-edge project of basic materials, which is also Zhang Shousheng's prediction. Maybe in the future integrated circuits, tinene will replace silicon materials instead of graphite. Because of the current research, tinene is better than graphene. )
