Abstract
We present the influence of the surface orientation on the band contribution to the segregation energy, within the tight-binding model, for fcc crystals. These results confirm that nondense surfaces favor the segregation, as experimentally observed. "Complex-energy-plane integration" for occupancy numbers, or energies, is also discussed.Keywords
