    Film-thickness-driven superconductor to insulator transition in cuprate superconductors
  11. 631
    “…Here we report colossal positive magnetoresistance (CPMR) (>30,000% at a temperature of 2 K and a magnetic field of 9 T) discovered in degenerate semiconducting strontium titanite (SrTiO(3)) single crystals capped with ultrathin SrTiO(3)/LaAlO(3) bilayers. The low-pressure high-temperature homoepitaxial growth of several unit cells of SrTiO(3) introduces oxygen vacancies and high-mobility carriers in the bulk SrTiO(3), and the three-unit-cell LaAlO(3) capping layer passivates the surface and improves carrier mobility by suppressing surface-defect-related scattering. …”

    Al-Doped SrMoO(3) Perovskites as Promising Anode Materials in Solid Oxide Fuel Cells
  14. 634
    “…Mo replaces W at both Wyckoff sites 4a and 48h and is evenly distributed, in contrast with La(6−y)WO(12−δ). X-ray absorption spectroscopy as a function of partial pressure pO(2) in the near-edge regions excludes oxidation state changes of Nd (Nd(3+)) and W (W(6+)) in reducing conditions: the enhanced hydrogen permeation, i.e. ambipolar conduction, observed in Mo-substituted Nd(6−y)WO(12−δ) is therefore explained by the higher Mo reducibility and the creation of additional – disordered – oxygen vacancies.…”
