Product Description

Description

ScAlMgO4(MgScAlO4SCAM) crystal is a kind of GaN and ZnO heteroepitaxy recently developed with the ideal substrate material, currently it match the GaN and ZnO best in the new substrate materials.ScAlMgO4 crystals are hexagonal system,which lattice constant a = 0.3246 nm, c = 2.5195 nm, with rhombohedron layered structure, similar to wurtzite nitrides and the structure of zinc oxide.ScAlMgO4 crystal is a kind of ideal substrate material for GaN and ZnO epitaxy, which is theminimum lattice mismatch with GaN and ZnO.
