GALLIUM PHOSPHIDE Usage And Synthesis

Chemical Properties

Pale-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 properties

Pale 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.

Uses

Galllium phosphide (GaP) is a light-colored highly pure crystal form used as “whiskers” and crystals in semiconductor devices.

Uses

In semiconductor electronics.

Preparation

The 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.
