We present a theoretical study of the modification of the one-hole spectra induced by the surface in YBa2Cu3O7. Basal plane surfaces terminated either with Ba or CuO planes are considered. Correlation effects are included by using a Hubbard model hamiltonian and by calculating the self-energy in the low density approximation. The results indicate that both the main bands and the satellites are sensitive to the choice of the surface.

Abstract

We present a theoretical study of the modification of the one-hole spectra induced by the surface in YBa2Cu3O7. Basal plane surfaces terminated either with Ba or CuO planes are considered. Correlation effects are included by using a Hubbard model hamiltonian and by calculating the self-energy in the low density approximation. The results indicate that both the main bands and the satellites are sensitive to the choice of the surface.
