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
