The satellite structure of YBa2Cu3O7 compound is calculated starting from an accurate description of the bulk band structure and evaluating the self-energy effects arising from the intra-atomic Coulomb repulsion on the copper and oxygen sites. A continuum of satellites of d8 character originating from the highly hybridized Cu-O bands is found between 8 and 13 eV binding energy. Comparison with the experimental data allows one to explain the behavior of the Cu satellites in resonant photoemission and provides indications about the intrinsic character of the satellite at 9 eV.

Abstract

The satellite structure of YBa2Cu3O7 compound is calculated starting from an accurate description of the bulk band structure and evaluating the self-energy effects arising from the intra-atomic Coulomb repulsion on the copper and oxygen sites. A continuum of satellites of d8 character originating from the highly hybridized Cu-O bands is found between 8 and 13 eV binding energy. Comparison with the experimental data allows one to explain the behavior of the Cu satellites in resonant photoemission and provides indications about the intrinsic character of the satellite at 9 eV.
