ELECTRONIC-STRUCTURE, MAGNETISM AND GROWTH OF ULTRATHIN FILMS OF TRANSITION-METALS

The conditions which determine the growth mode on a perfect surface are determined in terms of the electronic structure of ultrathin films and interfaces. The various contributions (elastic, structural, chemical, magnetic, ...) to the spreading energy-gamma-nu and to the interface energy gamma-1,nu are obtained at zero kelvin for one overlayer (nu = 1) of transition metal A on a transition metal B by using a tight binding model and the recursion method to get general trends. Special attention is devoted to the growth of peculiar magnetic overlayers.
