THE ELECTRONIC-STRUCTURE OF BI2-XGDXRU2O7 AND RUO2 - A STUDY BY ELECTRON-SPECTROSCOPY

Abstract:

The bismuth gadolinium pyrochlore ruthenates Bi2-xGdxRu2O7 have been studied in relation to RuO2 by the techniques of X-ray and ultraviolet photoelectron spectroscopy (XPS and UPS) and high-resolution electron-energy-loss spectroscopy (HREELS). The composition-dependent metal-to-semiconductor transition in the pyrochlore system is mirrored by the progressive decrease with composition parameter in (i) the density of electronic states at the Fermi energy in UPS, (ii) the plasmon frequency in HR...
