Abstract

A detailed analysis of the intensities of valence-band photoelectron features of superconducting YBa2Cu3O7-x and semiconducting La1.85Sr0.05CuO4 has revealed a resonance in the peak located at a binding energy of 9.5 eV for photon energies spanning the onset of O 2s excitations. This demonstrates conclusively that the feature is associated with oxygen excitations. The origin of the satellite is described and its disappearance on superconducting surfaces is explained. © 1989 The American Physical Society.
