Cover Picture: Structural Relaxation in Charged Metal Surfaces and Cluster Ions (Small 12/2006)

The cover picture shows the contour plot of the difference between the total electronic densities of the dianionic and neutral states of the Au₃₀₉ cluster, as predicted by density functional theory calculations. The excess charge of the dianion is located almost entirely outside of the outermost atom core positions. Investigations of such species can help the understanding of processes at charged surfaces and interfaces, for example, the forces and atomic relaxation at the interface of a metal electrode and an electrolyte.
