Semiconductor refers to a material with electrical conductivity between conductor and insulator at normal temperature.
Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors.
No matter from the perspective of science and technology or economic development, the importance of semiconductors is very great. The core unit of most electronic products, such as computers, mobile phones or digital recorders, is closely related to semiconductors.
Common semiconductor materials include silicon, germanium, gallium arsenide, etc. silicon is one of the most influential semiconductor materials.
