Abstract

Abstract Surface effects on the tight-binding parameters for electrons are examined in a very simple system that allows the analytical calculation of all the atomic integrals needed. In spite of the simplicity of the model various qualitative results are obtained. It is seen that the inclusion of electron-electron interaction is essential to characterize the variation of the tight-binding parameters near defects. Effects of surface relaxation are also modelled and useful conclusions are drawn.
