| Abstract: | The adsorption of one cesium atom on a (110) gallium arsenide surface is investigated by means of a molecular-orbital method. Several surface deformations are considered. The values obtained for the extraction energy of one electron, the net charge of cesium atom, and the adsorption energy, allow to infer that the cesium atom is placed above the surface in neighbourhood of a gallium atom. |
