    Blue and Yellow Luminescence in ZnO Films Grown by Peroxide MBE

    We observed strong shifts of the blue and yellow luminescence bands with variation of excitation intensity in ZnO films grown on sapphire by MBE using hydrogen peroxide as a source of reactive oxygen. The blue...

    Growth of High-Quality Pb(ZrxTi1-x)O3 Films by Peroxide MBE and Their Optical and Structural Characteristics

    The growth of Pb(ZrxTi1-x)O3 (PZT) films by molecular beam epitaxy was demonstrated. Single-crystal, single-phase PZT films were grown on (001) SrTiO3 substrates at a growth temperature of 600°C. In situ monitori...

    Morphology and Optical Properties of ZnO Nanorods Grown by Catalyst-Assisted Vapor Transport on Various Substrates

    ZnO nanorods were grown by catalyst-assisted vapor phase transport on Si(001), GaN(0001)/c-Al2O3, and bulk ZnO(0001) substrates. Morphology studies showed that ZnO nanorods grew mostly perpendicularly to the GaN ...
