CONDUCTANCE RESONANCE OF COUPLED SUPPORTED METAL-CLUSTERS

The conductance resonance of a tunneling structure with a few metal cl usters, deposited on an insulating film, is studied by the generalized Breit-Wigner formula in a tight-binding approximation. We find that i n the conductance resonance the multiple peak structure comes from the interaction between supported metal clusters on an insulating film an d that the different arrangements of metal clusters can cause a differ ence of the conductance resonance peaks. Therefore it is possible to p redict the effect of the interaction between metal clusters on the con ductance resonance and develop some new microelectronic devices by art ificially arranging metal clusters on the surface of the insulating fi lm.
