The first graphene functional semiconductor was born! The Chinese scientific research team leads the research and development
Some time ago, it was reported that a foreign research team created the world's first graphene semiconductor! As soon as this news was made public, it also caused a shock in the semiconductor industry, the graphene industry and the technology industry! The article was published in the journal Nature, and the title of the article translates to --"Ultra-high mobility semiconductor epitaxial graphene on silicon carbide"！
As we all know, most of the chips currently use silicon materials, but with the continuous reduction of chip size and the continuous improvement of the process level, silicon chips have almost reached the limit. TSMC and Samsung have already achieved mass production of 3nm chips, and ASML has provided Intel with the world's first 2nm lithography machine, so as we enter the 2nm and 1nm era, where does silicon chip go next?
Obviously, the tablet industry will start a new change, whoever finds new tablet materials first, who develops new tablet manufacturing technology first, who can overtake in the corner and become a new leader in the field of tablet computers. Western countries will not miss this opportunity to consolidate hegemony!
I thought that this time the Chinese research team was lagging behind again, but I didn't expect a reversal! And the rumors on the Internet that the foreign research team is responsible are also not in line with the facts, it turns out that the world's first functional graphene semiconductor is led by a Chinese research team, and the co-authors of ** are mainly from the research team of Tianjin University in China!
In fact, in the process of chip material selection and development, many materials have been eliminated, such as carbon-based materials. The reason why the research team chose graphene material was mainly attracted by its three characteristics, namely, it is strong and durable, can withstand high currents, and will not be marital and scattered! This also determines the huge application potential of graphene in the field of electronics.
But graphene has a drawback, and that is that it has no band gaps! What is Band Gap? To put it simply, when an electric field is applied, the band gap can be opened or closed, this is how all silicon electronic components work, and only when this problem is solved, graphene can replace silicon as the material for making semiconductors.
The research team made a very bold attempt to put atoms into graphene material and pass through this"Donate"method, the electronic properties of the material were successfully measured without damaging the material! The results show that graphene semiconductors are 10 times more mobile than silicon. This means that graphene semiconductors are faster, more efficient, and generate less heat. This discovery is of great significance for the development of the semiconductor industry!
The fact that a Chinese research team was able to lead this research also shows that China's science and technology are developing at a rapid pace in the field of cutting-edge technologies, although we have been playing a role in recent decades"Chasers"But every change is an opportunity, as long as you can control China's science and technology, there is a chance to catch up or even surpass! Tianjin University has done a very good job, and the success of this research has given a shot in the arm to China's semiconductor industry, and the future is bright!
