Figure 1From: Theoretical Investigations into Self-Organized Ordered Metallic Semi-Clusters Arrays on Metallic SubstrateThe average energies for the [(n − 1) × (n − 1)]/(n × n) Pb bilayer/Cu(111) (n = 2,3,…, 12) structures. The dark(big) and red(small) balls are for Pb and Cu atoms, respectivelyBack to article page
