abstract = {Local dissolution/deposition processes under in situ
scanning tunneling microscopy (STM) imaging conditions are
studied in the systems Ag(111)/Ag+, ClO4- and Ag(111)/Ag+,
SO42-. The results show that in both systems the local
kinetics of these processes strongly depend on the
polarization conditions. At STM-tip potentials more positive
than the Ag/Ag+ equilibrium potential, a local dissolution
of the Ag(111) substrate is observed even at cathodic
substrate overpotentials at which the overall substrate
current density is cathodic. This tip-induced Ag dissolution
is in agreement with results obtained recently in the system
Cu((111))/Cu2+. The enhanced local Ag dissolution is
explained by a reduced Ag+ concentration underneath the STM
tip promoted by both an electrostatic repulsion of Ag+ and a
reduction of the mass transport due to the shielding effect
of the tip. The possibility for a preparation of negative Ag
nanostructures by STM tip-induced electrochemical
dissolution is demonstrated. (C) 2003 Elsevier Science Ltd.
