Compound semiconductor is introduced

As compound semiconductor refers to the amorphous inorganic compound semiconductor, more is to point to by two or more elements to determine the ratio of atoms to form compounds, and has determined the forbidden band width and band structure of semiconductor properties. [1], including amorphous inorganic compounds (e.g., III, V, II - VI family compound semiconductor) and its solid solution, amorphous inorganic compounds (e.g., glass) semiconductor, organic compounds, such as organic semiconductors) and oxide semiconductor, etc. Mainly binary compounds such as gallium arsenide, indium phosphide, cadmium sulfide, bismuth telluride, cuprous oxide, etc., followed by the binary and multiple compounds, such as aluminum gallium arsenic, indium gallium arsenic phosphorus, phosphorus, selenium, copper indium gallium arsenide and some rare earth compounds (such as SeN, YN, La2S3, etc.). More bridgman method (a method) by melt growth of single crystal, lec, vertical gradient solidification process, compound semiconductor single crystal with extension method, chemical vapor deposition method such as the preparation of their film and compound thin layer microstructure of materials. Used for the preparation of optoelectronic devices, ultra-high speed microelectronics devices and microwave devices, etc.
