Molecular Beam Epitaxial Growth of ZnSe, ZnSSe and ZnMnSSe Layers on GaAs Substrates for Blue-Green Laser Structures
Published online by Cambridge University Press: 10 February 2011
Abstract
Single layers of ZnSe, ZnSxSe1−x., and Znl−y.MnySxSe1−x., were grown on the GaAs(001). Realtime reflection high energy electron diffraction was used to study the initial growth of ZnSe(001) on GaAs(001) under different conditions. Exposure of the GaAs substrate to Se flux before growth led to three-dimensional growth, whereas exposure to Zn flux led to two dimensional-growth. ZnSxSe1−x., and Znl−y.MnySxSe1−x., (energy gap less than 2.9 eV) layers with the lattice constant closely matched to that of GaAs have been grown with a good reproducibility.
