      abstract     = {Electrochemical equilibrium and the transfer of mass and
                      charge through interfaces at the atomic scale are of
                      fundamental importance for the microscopic understanding of
                      elementary physicochemical processes. Approaching atomic
                      dimensions, phase instabilities and instrumentation limits
                      restrict the resolution. Here we show an ultimate lateral,
                      mass and charge resolution during electrochemical Ag phase
                      formation at the surface of RbAg(4)I(5) superionic conductor
                      thin films. We found that a small amount of electron donors
                      in the solid electrolyte enables scanning tunnelling
                      microscope measurements and atomically resolved imaging. We
                      demonstrate that Ag critical nucleus formation is rate
                      limiting. The Gibbs energy of this process takes discrete
                      values and the number of atoms of the critical nucleus
                      remains constant over a large range of applied potentials.
                      Our approach is crucial to elucidate the mechanism of atomic
                      switches and highlights the possibility of extending this
                      method to a variety of other electrochemical systems.},
