| 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. | | Uses | Gallium 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. | | 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. |
