Transparent Orange Undopped GaP Wafers P Type N Type 200um 350um 5G Light Emitting

Description:

Gallium Phosphide GaP, an important semiconductor of unique electrical properties as other III-V compound materials, crystallizes in the thermodynamically stable cubic ZB structure, is an orange-yellow semitransparent crystal material with an indirect band gap of 2.26 eV (300K), which is synthesized from 6N 7N high purity gallium and phosphorus, and grown into single crystal by Liquid Encapsulated Czochralski (LEC) technique. Gallium Phosphide crystal is doped sulfur or tellurium to obtain n-type semiconductor, and zinc doped as p-type conductivity for further fabricating into desired wafer, which has applications in optical system, electronic and other optoelectronics devices. Single Crystal GaP wafer can be prepared Epi-Ready for your LPE, MOCVD and MBE epitaxial application. High quality single crystal Gallium phosphide GaP wafer p-type, n-type or undoped conductivity at Western Minmetals (SC) Corporation can be offered in size of 2″and 3” (50mm, 75mm diameter) , orientation <100>,<111> with surface finish of as-cut, polished or epi-ready process.

Applications:

Gallium phosphide single crystal through slicing, epitaxy and other processes can be made into solid light emitting devices, its life is long, is semi-permanent. This device has developed rapidly and is widely used in instruments, computers and electronic watches, etc., for digital display or indicator light, it can emit red or green light, etc. (the luminous wavelength varies with doping). Early light-emitting devices made of gallium arsenide needed a current of 100 milliamps to emit 20 millilumens per word. The same light-emitting device made of gallium phosphide requires only 10 milliamps of current to emit 20 millilumens. The efficiency of gallium phosphide light-emitting tube made by two-layer epitaxy method is 4-5%. Wingloff believes that the main factor affecting the efficiency of gallium phosphates light-emitting devices is the dislocation density in the crystal, and the luminous efficiency is low when the dislocation density is high.
