Using a first-principles method based on density functional theory, we investigate the surface relaxation and electronic states of Au(100), ( 110) and ( 111) surfaces. The calculated results show that the relaxations of the ( 100) and ( 110) surfaces of the metal are inward relaxations. However, the
The mean-square displacements in three directions for the atoms of the Ni(ll0) surEace are calculated by means of a simplified treatment, using a Morse potential function. Taking into account a surface relaxation, the theoretical results are in good agreement with the experimental data. Mean-square
