Figure 1From: Low-energy structures of clusters supported on metal fcc(110) surfaces Low-energy structures of cluster n = 15 (a) on Cu(110) and (b) on Pt(110) surface. From structures 1 to 7, the energy is increasingly higher. The nearest-neighbor (NN), next nearest-neighbor (NNN), and third nearest-neighbor (TNN) bonds are indicated in (c).Back to article page
