Abstract

Growth of II-VI and III-V nitrides by MBE and MOCVD is being studied. Using GaAs as a buffer and ZnMgSSe quaternary alloy as a cladding layer together with a ZnSe/ZnTe superlattice for ohmic contact, room temperature CW operation of II-VI lasers has been achieved. Focus topics include the (1) optical properties of ZnSe-based epilayers, (2) the effect of GaAs buffer surface construction and initial growth condition of ZnSe on the defect density and (3) etch-pit configuration of different type of defects in ZnSe-based epilayers. Multilayer p-GaN/MQW GaN-In_0.1GaN/n-GaN were grown on sapphire substrate using MOVPE and plasma-assisted ionized source beam epitaxy. We investigated the (1) growth and properties of III-V nitride films by LP-MOVPE and PAMBE (Plasma Assisted Molecular Beam Epitaxy), (2) etch-pit and wet etching of GaN/(0001)Al₂O₃, (3) ohmic contacts of GaN and (4) GaN etching by CARIBE.
