    Microscopic structure and structuring of perovskite surfaces and interfaces: SrTiO3, RBa2Cu3O7-δ

    surfaces and bicrystal interfaces and the growth of YBa2Cu3O7-δ thin films on such substrates using scanning tunneling microscopy and X-ray diffraction. Proper annealing of SrTiO3 in oxygen and/or ultrahigh vacu...

    Local lattice anomalies in underdoped YBa2Cu3O7-Σ probed by X-ray absorption fine structure

    Temperature-dependent local lattice anomalies in underdoped YBa2Cu3O7-Σ are studied by extended X-ray absorption fine structure (EXAFS) in a fluorescence mode. The in-plane polarized Cu A^-EXAFS is measured on un...

    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...

    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 ...
