XPS and UPS photoemission experiments on the highTc superconductors (Tc≈90 K) with nominal composition YBa2Cu3O9-y (y≈2) show the following: a) The density of electronic states at the Fermi energy is very small, much smaller than in pure Cu. b) T

A number of theoretical models have been developed to explain the unexpected high temperature superconductivity in La-Me-Cu-oxides (Me=Ba, Sr) and Y-Ba-Cu-oxides. Some of these models invoke charge fluctuations on the copper ions in the superconducto

The oxidation of polycrystalline Zr under 10−8-10−3 mbar oxygen pressure in the temperature range 25 °–350 ° C is obtained from ESCA experiments. Changes in the ESCA spectra for thin Zr films on Ag oxidized at 250 ° C are observed and compar

From XPS core level spectroscopy the average copper charge on the Cu sites in the high temperature superconductor Y1Ba2Cu3O7−x is determined as function of the oxygen vacancy concentrationx. Analysis of these data leads to the suggestion that there
