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 .
