THE ELECTRONIC STRUCTURE OF THE COVALENT CRYSTALS SURFACES WITH ADSORBED METALS

The object of investigation: the unconstructed and reconstructed surfaces of the covalent metals. The purpose of the work: the development of the effective diagram for the determination of the electronic spectre of surfaces, the analysis of interconnection between the peculiarities of the electronic spectre and ustability of the surface relative to the reconstruction. The algorithm for finding the low-lying own values of the matrix of large dimension has been offered. Studied have been the electronic spectres of surfaces (001)-1x1, (001)-2x1, (III)-1x1 of the covalent metals and the degree of coating. The influence of the temperature factor on the electronic spectre has been investigated. The electronic spectres of the clean and with the adsorbed metals surfaces of the covalent crystals, to be widely used in microelectronics, have been designed. The unstability (stability) of the surface relative the reconstruction corresponds to metal (dielectric) type of the electronic surface spectre. The field of application: it is recommended to use in the organisations, dealing with the development of materials, intended for the electronic techniqueAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
