CY2299 LSAT Crystal Substrates

Description of LSAT Crystal Substrates

Compared with the more commonly used high-temperature superconducting thin-film LaAlO3 crystal, (La, Sr) (Al, Ta) O3 (referred to as LSAT) has the same crystal structure, and the phase transition temperature is low, and twins are not easy to appear, this excellent high temperature superconducting thin film substrates are gradually recognized. At the same time, its <111> direction has the same hexagonal symmetry as GaN, so it can be used as a substrate material for GaN and AlN films.
