Product Description

2-6 inch Gallium phosphide (GaP) crystals crystal substrate,GaP wafer


 ZMKJ can provides high quality single crystal GaP wafer ( Gallium phosphide ) to electronic and optoelectronic industry in diameter up to 2 inch . Gallium phosphide ( GaP ) crystal is an orange-yellow semi-translucent material formed by two elements , Gallium and Phosphide , growth by Liquid Encapsulated Czochralski ( LEC ) method . GaP wafer is an important semiconductor material which have unique electrical properties as other III-V compound materials and is widely used as red , yellow , and green LED ( light-emitting diodes ) . We have as-cut single crystal GaP wafer for your LPE application , and also provide epi ready grade GaP wafer for your MOCVD & MBE epitaxial application . Please contact us for more product information .
