摘要：

By performing current-image tunneling spectroscopy at room temperature, we have observed the staircase current-voltage (I-V) characteristic and negative differential conductance on a single Ag cluster on a clean GaAs(110) surface. The I-V characteristics have changed spatially with the position of the tip on the cluster. The characteristics are understood in terms of Coulomb blockade and resonance of electron standing-wave states in the cluster with the states of the underlying substrate.
