GALLIUM PHOSPHIDE Usage And Synthesis
Chemical PropertiesPale-orange, transparent crystals or whiskers up to 2 cmlong, made by vapor phase reaction at relatively low temperatures between phosphorus and gallium suboxide. These crystals are intermediate between normal semiconductors and insulators or phosphors. They operate over a temperature range of ?55 to 500C. Gallium phosphide is electroluminescent in visible light.
Physical propertiesPale orange to yellow transparent cubic crystals or long whiskers; lattice constant 5.450?; density 4.138 g/cm3; melts at 1,477°C; dielectric constant 8.4; electroluminescent in visible light.
UsesGalllium phosphide (GaP) is a light-colored highly pure crystal form used as “whiskers” and crystals in semiconductor devices.
UsesIn semiconductor electronics.
UsesGallium phosphide (GaP) is used in semiconductor devices, and in the manufacture of light-emitting diodes (LEDs) doped with other elements or in combination with gallium arsenide phosphide. With appropriate dopants, p-type and n-type semiconductors can be produced. It is used in optical systems.
PreparationThe compound is prepared by vapor phase reaction of gallium suboxide, Ga2O and phosphorus. It is produced in polycrystalline form or as single crystals or whiskers in high purity grade for use in semiconducting devices.
