Abstract

The formation of well‐ordered 2‐D metal adsorbate layers in the underpotential (UPD) range and 3‐D metal deposits in the overpotential (OPD) range on foreign substrates was studied in the model system Ag(hkl)/Pb2+ by in situ STM under defined potential control with lateral atomic resolution.
