Theory of surface segregation in transition metal alloys and hydrides

The surface segregation is calculated in the coherent-potential approximation. The influence of the surface potential, d-band fillings and d-level splitting of alloys components on the segregation is examined for a model density of states. The realistic tight-binding Hamiltonian is used to calculate the segregation for Cu-Ni alloys. The model for all reasonable values of parameters predicts the segregation of copper for all alloy compositions.
