    Anisotropic Terahertz Emission from Bi2Se3 Thin Films with Inclined Crystal Planes

    We investigate the surface states of topological insulator (TI) Bi2Se3 thin films grown on Si nanocrystals and Al2O3 substrates by using terahertz (THz) emission spectroscopy. Compared to bulk crystalline Bi2Te2S...

    Nucleation and growth of primary nanostructures in SrTiO3 homoepitaxy

    SrTiO3 nanoislands on SrTiO3 (001) in a diffusion-limited growth regime were studied using in situ scanning tunneling microscopy (STM). The STM images revealed two characteristic features of nucleation stages. Fi...

    Catalytic activities of noble metal atoms on WO3 (001): nitric oxide adsorption

    Using first-principles density functional theory calculations within the generalized gradient approximation, we investigate the adsorption of NO molecule on a clean WO3(001) surface as well as on the noble metal ...

    Magnetic and electric properties of stoichiometric BiMnO3 thin films

    It has been suggested that BiMnO3 is a material exhibiting both ferromagnetism and ferroelectricity. Stoichiometry is rather easily achieved in a polycrystalline sample, and ferromagnetic properties have been wel...

    Performance evaluation of multi-junction solar cells by spatially resolved electroluminescence microscopy

    An electroluminescence microscopy combined with a spectroscopy was developed to visually analyze multi-junction solar cells. Triple-junction solar cells with different conversion efficiencies were characterize...

    Morphology and magnetic properties of Fe3O4 nanodot arrays using template-assisted epitaxial growth

    Arrays of epitaxial Fe3O4 nanodots were prepared using laser molecular beam epitaxy (LMBE), with the aid of ultrathin porous anodized aluminum templates. An Fe3O4 film was also prepared using LMBE. Atomic force m...
