    Size effects on the crystal structure of nanoscale BaTiO3 powders prepared by hydro-thermal synthesis

    The size effect on crystal structure has been investigated for nanoscale BaTiO3 powders prepared by hydrothermal methods. The powders were composed of both the cubic and tetragonal phases at room temperature. The...

    Investigation of the structural defects in GaN thin films grown by organometallic vapor phase epitaxy

    GaN thin films were prepared on {0001} planes of sapphire substrates by organometallic vapor phase epitaxy (OMVPE) techniques. The crystall orgaphic relation between the film and the substrate as well as the s...

    Structural features of tilt grain boundaries in GaAs thin films

    (fa181-1) and low-angle tilt grain boundaries in GaAs thin films were investigated by high-resolution transmission electron microscopy (HRTEM). Models for the atomic structure of the boundaries are proposed in...
