摘要：

The transport properties of Ag-n clusters, 40 < n < 100, deposited on crystalline graphite and probed with a tunneling tip are analyzed by using non-equilibrium Green's functions. Current-voltage characteristics are computed accounting for self-consistent charge redistribution in the cluster caused by coupling to the surface and the external bias. The differential conductance is compared to the density of states of the supported clusters at equilibrium, highlighting the effects of charging and substrate properties on the measured spectrum.
