Electronic structure of epitaxial monolayers

Several authors have studied the electronic structure of interfaces resulting from a two-dimensional epitaxial growth of metallic layers on an oxide surface. 

On the (0001) face of a-alumina covered with one niobium, zirconium, molybdenum, ruthenium or palladium monolayer, Ohuchi and Koyama (1991) have shown that the metal d band is located in the energy range of the alumina gap. It is hybridized with the oxygen states of the valence band. In the series, more and more anti-bonding d states are filled, which yields results in agreement with the cluster calculations quoted above. 

The electronic and geometric characteristics of the Ag-MgO(lOO) interface have aroused much interest. Freeman et al. (1990), Blochl et al. (1990) and Li et al. (1993) have found that the silver atoms are more

Theoretical studies have been devoted to various aspects of the first stages of deposition, such as the electronic structure of supported clusters, the electronic structure of epitaxial monolayers and the modelling of growth modes.
