Silicon materials are divided into monocrystalline silicon and polycrystalline silicon based on the arrangement of their crystal cells. The main difference between monocrystalline and polycrystalline silicon is that the crystal cell arrangement in monocrystalline silicon is ordered, while that in polycrystalline silicon is disordered. In terms of manufacturing methods, polycrystalline silicon is generally made by … Read more

Semiconductor materials are a class of materials that possess semiconductor properties (the conductivity is between that of conductors and insulators, with resistivity ranging from approximately 1 mΩ·cm to 1 GΩ·cm). Generally, the conductivity increases with rising temperature. Semiconductor materials have characteristics such as thermal sensitivity, optical sensitivity, and doping capability. They are important materials used … Read more
