ABSTRACT

We investigate the structure and energetics of Na clusters on Na-Cl surfaces. The Na-Cl substrate is taken as inert acting on the clusters constituents essentially through its interface potential which consists in a general surface attraction and is modulated by corrugation. The cluster is described as a predominantly electronic system in the spirit of the ultimate jellium model. The strong surface attraction makes planar clusters the preferred choice in any case and non-planar stable isomers do always exist. The corrugation has a large influence on the shapes, particularly for the larger clusters. But the total energy of the clusters is insensitive to these details. It can be described in terms of volume, surface, and interface energy allowing a simple estimate of the preferred geometry in dependence of the strength of the interface potential. More... »
