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. 000046694 536__ $$0G:(DE-Juel1)FUEK242$$2G:(DE-HGF)$$aKondensierte Materie$$cM02$$x0 000046694 588__ $$aDataset connected to Web of Science 000046694 650_7 $$2WoSType$$aJ 000046694 65320 $$2Author$$aScanning Tunneling Microscopy 000046694 65320 $$2Author$$aSTM-tip shielding effect 000046694 65320 $$2Author$$asilver deposition 000046694 65320 $$2Author$$atip-induced dissolution 000046694 7001_ $$0P:(DE-HGF)0$$aMayer, C.
