Abstract

A new method of obtaining spectroscopic information about clusters is realized though the interplay between the surface states at a metal-semiconductor interface and the discrete electronic energy levels of nanosize Pb clusters. When these surface states come into registry with the energy levels of the cluster, resonant peaks emerge in the I(V) characteristics. The histograms of the peak intensities and spacing are consistent with the Porter-Thomas and Wigner-Dyson distributions, respectively.
