Size-dependent field-emission spectra from nanometer-size supported gold
Physical Review B-Condensed Matter, vol.46, no.23, 15 Dec. 1992,
The energy spectra of electrons field emitted from individual, supported Au
clusters have been measured as a function of cluster size. Data are presented
for clusters with nominal diameters in the range 1.3-3.2 nm. For the smallest
clusters, the energy of the field-emitted electrons lies below the Fermi
level of the substrate and fine structure in the energy distribution is
observed. As the cluster size increases, the energy distribution shifts
toward the Fermi level of the substrate and the fine structure disappears.
