LiAlO2 (Lithium Aluminate) crystal is the most important substrate for the high-temperature superconducting thin film. It matches very well with high temperatures superconducting materials such as YBaCuO and has the characteristics of low dielectric constant and low microwave loss. LiAlO2 is a potential substrate for III-V nitride thin films due to its excellent lattice match to GaN, chemical stability at high temperature and cost effective than ZnO. LiAlO2 crystal can replace ZnO and sapphire as optical substrate. Lithium Aluminate (LiAlO2 ) single crystal has a lower lattice mismatch with GaN crystal to be an excellent substrate for GaN film.
