Abstract

A method; by which periodic two-dimensional arrays of identical metal clusters of nanometer size and spacing could be spontaneously obtained by taking advantage of surface mediated clustering; is reported. The versatility of the method is demonstrated for a broad range of metals on Si(111)-(7Ã7) substrates. In situ scanning tunneling microscopy analysis of In clusters; combined with first-principles total energy calculations; unveils unique initial-stage atomic structures of the surface-supported clusters and the vital steps that lead to the success of this method. A strong interaction between the clusters and the surface holds the key to the observed cluster sizes.
