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.
Whether from the perspective of science and technology or economic development, the importance of semiconductors is very great. The core units of most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors.
Common semiconductor materials include silicon, germanium, gallium arsenide, etc. silicon is the most influential one in the application of various semiconductor materials.
Semiconductor refers to the material whose conductivity is between conductor and insulator at room temperature. Semiconductor is a material with controllable conductivity, ranging from insulator to conductor. From the perspective of science, technology and economic development, semiconductors affect people's daily work and life. It was not until the 1930s that this material was recognized by the academic community.
