摘要：

The energies of clusters composed of a nitrogen atom adsorbed at different positions on iron(111), (100) and (110) surfaces were estimated with the aid of the Extended Hückel Theory method. The calculations show that on the Fe(111) surface the underlayer adsorption takes place mainly via an unactivated process. For the Fe(100) surface the underlayer and overlayer adsorption energies are nearly equal and transition from one adsorption type to the other requires activation energy. At the Fe(110) surface the overlayer adsorption of nitrogen is predominant. © 1990.
