제목 Molecular Beam Epitaxy of ZnSe/ZnTe superlattice buffer layers for the growth of antimonides thin films
초록 Molecular beam epitaxy (MBE) of high quality GaSb films on GaAs (001) substrates is achieved by inserting a ZnTe/ZnSe superlattice (SLS) buffer layer. The growth condition for the ZnTe/ZnSe SLS buffer was optimized in terms of in-situ RHEED intensity observation. We have compared the quality of GaSb layer grown on GaAs and ZnTe/ZnSe SLS, and the role of ZnTe/ZnSe SLS buffer layer is discussed. The crystal quality and surface morphology of grown films were investigated by high resolution X-ray diffraction measurement (HR-XRD), atomic force microscopy (AFM) of GaSb films.
