Metal-nonmetal transition in LixCoO2 thin film and thermopower enhancement at high Li concentration
Y. Ishida, A. Mizutani, K. Sugiura +2
We investigate the transport properties of LixCoO2 thin films whose resistivities are nearly an order of magnitude lower than those of the bulk polycrystals. A metal-nonmetal trans…

Potential Profiling of the Nanometer-Scale Charge Depletion Layer in n-ZnO/p-NiO Junction Using Photoemission Spectroscopy
Y. Ishida, H. Ohta, M. Hirano +2
We have performed a depth-profile analysis of an all-oxide p-n junction diode n-ZnO/p-NiO using photoemission spectroscopy combined with Ar-ion sputtering. Systematic core-level sh…

Temperature Dependence of the Chemical Potential in NaxCoO2: Implications for the Large Thermoelectric Power
Y. Ishida, H. Ohta, A. Fujimori +1
We have performed a temperature-dependent photoemission study of a NaxCoO2 (x~0.8) epitaxial thin film prepared by the reactive solid-phase epitaxy method. The chemical potential s…
