摘要：
Oxygen adsorption on Ag(110) surface has been investigated by means of first-principles total-energy and force calculations for repeated-slab geometries within the local density approximation (LDA). The added row model composed of oxygen atom and silver atom has been believed to be one of the most realistic models. We have already obtained the optimized geometry of the added row model. Using the optimized positions, the simulation of STM images and STS spectra has been performed based on the Bardeen's perturbation theory. Compared with the experimental data, the theoretical results seem to show a fairly good correspondence.
