Abstract
The changes in the electronic structure of the surface layer of a semicondu ctor substrate have been studied with allowance made for the indirect and d ipole-dipole interactions between adatoms. The conditions for the formation and suppression of gaps in the energy band of surface states of the substr ate are determined as a function of the adatom coverage of the surface. The results obtained are used in the interpretation of the metal-semiconductor transitions upon adsorption of cesium and sodium atoms on the Si(001) surf ace. (C) 2000 MAIK "Nauka/Interperiodica".
