Application

LiGaO2 substrate and GaN film are well matched, and can obtain a good gallium nitride film

 

Lithium gallate LiGaO2 single crystal substrate have a very good lattice matching for GaN (mismatch < 0.2%), and are chemically stable at high temperatures and low in cost , thus becoming a potential III-V Nitride thin film substrate material.
 
Lithium gallate(LiGaO2 ) and lithium aluminate(LiAlO2) single crystal are the best substrate materials for matching with GaN epitaxial films. GaN films are the basis for the current production of blue, violet, ultraviolet light-emitting diodes and solid-state white light sources.
