摘要: The molecular orbital description of silver clusters presented here is based on EHT calculations and shows that the most stable Agn small are planar. This result represents a striking difference from what was found for some transition metal clusters. Ag6 cluster (D3h symmetry) which has highest compactness compatible with planar structure remarkably stable. seems to be driving force guiding growth aggregates. It leads monolayer structures high stability. These monolayers do not easily couple form 2D thin slabs even though thickest slabs, remembering stability fcc bulk metal, An alternate formation closed two-dimensional surfaces. Favorables intermediates along this line 18 hollow spheroid 42 icosahedron.
