      abstract     = {The electrocrystallization process was studied in the
                      system Ag(111)1Ag(+). SO4= by in situ scanning tunneling
                      microscopy (STM). The results show that Ag deposition occur
                      preferentially at step edges following a layer-by-layer
                      growth mechanism, but polarization and imaging conditions
                      Greatly affect the local kinetics of this process. At
                      STM-tip potentials more positive than the Ag/Ag- equilibrium
                      potential. a local dissolution of the substrate underneath
                      the tip is observed even at low negative substrate
                      overpotentials, at which the overall substrate current
                      density is cathodic. An in sire STM imaging of Ag deposition
                      was possible at sufficiently high negative substrate
                      overpotentials. An estimation of the local deposition
                      current density, however. indicates that the deposition rate
                      underneath the STM-tip is reduced. These results are
                      explained by the presence of an electric field between the
                      STM-tip and the substrate, which affects the potential
                      distribution directly underneath the tip. producing a large
                      shielding of the diffusive flux of Ag+ ions.},
