We present the results of theoretical calculations of the surface electronic structure of YBa2Cu3C7 assuming different crystal terminations. Through a detailed analysis of the distribution of the valence charge near the surface we show that hole distribution may be significantly modified at the surface, due to the band narrowing and to the presence of surface states. The role of these modifications in determining the shape of the one-hole spectra is discussed.

Abstract

We present the results of theoretical calculations of the surface electronic structure of YBa2Cu3C7 assuming different crystal terminations. Through a detailed analysis of the distribution of the valence charge near the surface we show that hole distribution may be significantly modified at the surface, due to the band narrowing and to the presence of surface states. The role of these modifications in determining the shape of the one-hole spectra is discussed.
