Using scanning tunneling microscopy, Coulomb blockade of tunneling ele
ctrons was realized on a simple metal/semiconductor system, by taking
a sample of individual Ag clusters formed on the clean GaAs(110) surfa
ce, The second barrier of a two tunneling junction is at a space inter
val at the Ag/GaAs(110) interface, which is naturally formed due to a
lattice match of the cluster and the GaAs(110) substrate. Images of di
fferential conductance taken of the clusters by current image tunnelin
g spectroscopy (CITS) demonstrate that the electron tunneling is close
ly related to detailed atomic structures of the clusters. (C) 1998 Els
