ABSTRACT
Coherently strained In0.5Ga0.5N on GaN and CaO substrates are theoretically predicted to show stable ordering in the chalcopyrite structure, as is Ga2AsSb on GaAs and InP substrates. Depending on the substrate and the film concentration, we predict a spontaneous rotation of the stablest chalcopyrite film axis from perpendicular to parallel to the (001) substrate.

    We analyze the surface morphological stability of a coherently strained thin film grown epitaxially on a thick elastic substrate under the simultaneous action of an electric field that drives surface electromigration. A model of driven film surface morphological evolution is developed and a...

    Epitaxial ZnO thin films were grown on r-plane sapphire substrates using plasma-assisted molecular-beam epitaxy. ZnO homobuffer layers grown at a lower temperature were introduced to improve the crystallinity of the top ZnO thin films. Thicker homobuffer layers lead to better crystallinity of...

    Interfacial structure and chemistry of epitaxial CoFe2O4 thin films on (001)_SrTiO3 and (001)_MgO substrates were investigated using high-angle-annular-dark-field imaging combined with electron-energy-loss-spectra (EELSs) analyses at a subnanometer scale. The results show that CoFe2O4/SrTiO3...

    Epitaxial thin films of BiScO3—a compound thermodynamically unstable under ambient conditions—were grown on BiFeO3-buffered SrTiO3 substrates. X-ray diffraction confirmed the reasonable crystalline quality of the films with a full width at half maximum of 0.58° in ω (004...

    Nanogrowth twins (GTs) have been observed in CoFe2O4 (CFO) epitaxial thin films deposited on (111) oriented SrTiO3 substrates by pulsed laser deposition. The GTs form during nucleation and growth and consist of CFO growth regions that have a mirror relationship with respect to each other. We...
