    Structure of a model TiO2 photocatalytic interface

    The interaction of water with TiO2 is crucial to many of its practical applications, including photocatalytic water splitting. Following the first demonstration of this phenomenon 40 years ago there have been num...

    X-ray standing wave investigations of Si dopant incorporation in GaN

    The synchrotron radiation technique of x-ray standing waves (XSW), which allows to directly obtain structural and element-specific data, was successfully used for the investigation of the dopant site distribut...

    Atomic Scale Engineering of SrTiO3 Single Crystal Surfaces and Bicrystal Boundaries for Epitaxial Growth of Oxide Thin Films

    We introduce a new annealing procedure to prepare well defined surfaces of SrTiO3 single crystal and bicrystal substrates. Annealing SrTiO3 (001) substrates in oxygen and then in ultra high vacuum produces a unif...

    A titanium-rich (111) surface of SrTiO3 single crystals by thermal annealing

    A very smooth (111) titanium-rich surface was obtained by annealing SrTiO3 single crystals in UHV. The surface structure was investigated with SEM, STM and LEED and was found to consist of terraces, interrupted b...

    In-Plane Asymmetries on the Ge(111)-c(2×8) Surface Mapped with the Scanning Tunneling Microscope

    We report on new experimental studies of the Ge(111)-c(2×8) reconstruction performed with low-energy electron diffraction. (LEED) and scanning tunneling microscopy (STM). Weak quarter-order reflections are pre...

    Determination of lattice mismatch in NiSi2 overlayers on Si(111)

    We determined the perpendicular overlayer mismatch for type A and type B NiSi2 samples of thicknesses ranging from about 200 to 1000 Å via bulk x-ray diffraction. An increase in the density of dislocations which ...
