Monocrystalline silicon generally refers to a substance formed by an arrangement of silicon atoms. The conductivity of semiconductors is between conductors and insulators. Silicon, germanium, gallium arsenide and cadmium sulfide are all semiconductor materials. The resistivity of semiconductor ma...

According to statistics, in 2020, the production capacity of Chinese polysilicon materials enterprises is about 470,000 tons, and the overseas production capacity is about 5,000 tons. The output of polysilicon materials in 2020 is expected to be about 390,000 tons, and the annual polysilicon impo...

Silicon carbide (SiC) is very rare in the natural environment. It was first discovered in meteorites in the solar system 4.6 billion years ago, so it is also called “semiconductor material that has experienced 4.6 billion years of time travel.” Compared with traditional silicon device...
