Common semiconductor materials are silicon, germanium, gallium arsenide, etc. Silicon is the most influential one in the application of various semiconductor materials.
Semiconductor materials are a class of electronic materials with semiconductor properties, whose electrical conductivity is between a conductor and an insulator, and the resistivity is in the range of 1mΩ·cm ~ 1GΩ·cm or 10(U-3) ~ 10(U-9) ohms\/cm. The electrical properties of semiconductor materials are very sensitive to changes in external factors, and their electrical conductivity can be controlled by adding a small amount of impurities. Semiconductor materials can be used to make semiconductor devices and integrated circuits. Common semiconductor materials include silicon, germanium and other diamond structure materials.
