Semiconductor has the characteristics of dopability, thermal sensitivity, photosensitivity, negative resistivity temperature, commutability.

In addition to manufacturing large-scale integrated circuits, semiconductor materials can also be used for power devices, photoelectric devices, pressure sensors, thermoelectric refrigeration and other purposes. The use of microelectronic ultrafine processing technology can also be made into MEMS (micro-mechanical electronic system), which is applied in the electronic and medical fields.

Semiconductors are materials that guide electrical properties between conductors and insulators. By adding impurities to change its electrical conductivity, artificially control whether it conducts electricity or not and how easily it conducts electricity.
