      abstract     = {The fluctuations of steps and the shapes of islands on
                      metal surfaces generally depend strongly on the electrode
                      potential, an effect that has been attributed to the
                      interaction of local surface dipole moments with the
                      double-layer field. In order to understand the details of
                      this effect,we have calculated the relevant energies and
                      dipole moments for the diffusion processes that govern the
                      fluctuations of steps and island shapes on Ag(1 0 0). The
                      corresponding rates have been used in kinetic Monte-Carlo
                      simulations to explore the dynamics of these structures. Due
                      to the field-dipole interactions the mobility of the surface
                      becomes larger with increasing electrode potential. Fourier
                      analysis allows us to determine the step stiffness and the
                      kink energy, and from the shape of the islands we have
                      obtained the line tension. All three quantities decrease
                      with increasing double-layer field. (C) 2009 Elsevier Ltd.
