      abstract     = {Using impedance spectroscopy, we determined the step dipole
                      moment and the potential dependence of the step line tension
                      of silver electrodes in contact with an electrolyte: (0 0 1)
                      and vicinal surfaces (1 1 n) with n = 5 7, 11 in 10 mM
                      ClO4--solutions were investigated. The step dipole moment is
                      determined from the shift of the potential of zero charge
                      (pzc) as a function of the Surface step density. The dipole
                      moment per step atom Was found to be 3.5 +/- 0.5 x 10(-3) e
                      angstrom. From the pzc and the potential dependence of the
                      capacitance curves, the potential dependence of the surface
                      tension of the vicinal Surfaces is determined. The line
                      tension of the steps is then calculated from the difference
                      between the Surface tensions of stepped (1 1 n) and the
                      nominally step-free (0 0 1) Surfaces. The results are
                      compared to a previous Study on Au(1 1 n) surfaces. For
                      gold, the step line tension decreases roughly linear with
                      potential, whereas a parabolic shape is observed for silver.
