Fig.5. STM image of an Ag(ll 1) surface in 10 mM NaF +0.1 mM Na2S. E = -0.75 V/SCE and Etip = 250 mV with It = 1.5 nA and a W tip.

epitaxy [13], is the electrochemical analogue of atomic layer epitaxy. STM is invaluable in the elucidation of the structures resulting from these alternate underpotential depositions.
