In 22, China made many remarkable achievements in the field of science and technology, such as the completion of the satellite network of Beidou-3, the world record of 1,-meter dive of the deep-sea submersible Endeavor, the quantum superiority of China achieved by the quantum computer in Chapter Nine and the successful landing of Chang 'e-5 on the moon, which made the world witness the "China miracle" again and again. At the same time, the Chinese Academy of Sciences once again sent good news that China's graphene single crystal technology broke international barriers and achieved a breakthrough.

When this news came out, Americans' faces became very ugly. Why?
It turns out that this technology can not only help the chip to shorten the time required for signal processing by 1 times, but also be used to manufacture terahertz radar, which can make American fighter planes suddenly lose their stealth function, so that American media said: Is there anything that China people can't do?
speaking of graphene, it is almost well known, and its excellent electrical and mechanical properties are regarded as one of the strongest crystals in the world. It is widely used in electronic chips, optical instruments, biomedical, electromagnetic and sensor fields. It can be said that it will be a widely used new material in the future, whether in military or civil use, and its prospects are broad.
graphene is called "universal superconducting material" because of its wide application and powerful performance. What worries the United States, however, is the application of graphene in chips and radar, which are two representative products of American science and technology and military respectively. If the United States loses these two advantages, its dominance will no longer exist, so when the Chinese Academy of Sciences announced a major breakthrough in graphene single crystal technology, the United States immediately began to worry.

So how does graphene shake the hegemony of the United States?
As we all know, traditional chips are made of silicon-based materials, while Chinese Academy of Sciences has made carbon-based chips with graphene as a new material, so the performance of these two chips is different because of their different materials. Graphene chip has stronger ability to process electrical signals than traditional silicon-based chips, and its stability has also been greatly improved.
At the International Graphene Innovation Conference held in Shanghai on October 16th, 22, Chinese Academy of Sciences showed us the latest achievement of 8-inch graphene single crystal wafer, which is at the leading level in the world in size and performance. It can be said that the large-scale use of this new material in the future will change the current pattern of silicon-based chips in the United States, and China chips will no longer be stuck.
In addition, there are other good news about chips in China. After seven years of unremitting efforts, the Peng Lianmao team of Peking University finally developed a 5-nanometer carbon nanotube, which is the smallest high-performance transistor in the world. The breakthrough of this technical bottleneck by Chinese Academy of Sciences has accelerated the development of carbon-based chips in China. At present, the total number of related patents has been far ahead of all countries in the world, and the annual output of graphene has reached 3 tons. It can be said that China has taken the lead in the field of graphene and will definitely dominate the global graphene industry in the future. (Breeze)
