Abstract

The stability of bimetallic nanoclusters fabricated using scanning tunneling microscopy methods is investigated using a phenomenological formalism, and the cohesive energies of Au-Cu, Au-Pd, and Ag-Cu systems are estimated. The influence of chemical hardness, composition of the substrate, and metal adatoms in the nanocluster as well as the dissociation energies of S-S and S-M bonds as regards the stability of nanoclusters is demonstrated.
