S. Vlaev, WEAKENING OF THE INTERACTION BETWEEN ADATOMS IN ONE-DIMENSIONAL METAL-CLUSTERS ADSORBED ON METAL SUBSTRATES, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 26, 1993, pp. 36-38
A semi-empirical Anderson-Newns-Grimley model is applied to consider t
he decreasing of the binding energy per atom in one-dimensional metal
clusters on metal supports as a result of the adatom-substrate bond. D
imer, linear trimer and infinite chain are studied. The competition be
tween the adatom-adatom and the adatom-substrate ineraction is reveale
d. A comparison with experimental measurements and other theoretical c
alculations is made.
