      abstract     = {By employing numerical solutions of the Poisson-Boltzmann
                      equation we have studied the interface capacitance of flat
                      electrodes with stripes of different potentials of zero
                      charge phi(pzc). The results depend on the ratio of the
                      width of the stripes l to the dielectric screening length in
                      the electrolyte, the Debye length d(Debye), as well as on
                      the difference Delta phi(pzc), in relation k(B)T/e. As
                      expected, the capacitance of a striped surface has its
                      minimum at the mean potential of the surface if l/d(Debye)<<
                      1 and displays two minima if l/d(Debye)>> 1. An unexpected
                      result is that for Delta phi(pzc)congruent to 0.2V, the
                      transition between the two extreme cases does not occur when
                      l congruent to d(Debye). but rather when l>10d(Debye). As a
                      consequence, a single minimum in the capacitance is observed
                      for dilute electrolytes even for 100 nm wide stripes. The
                      capacitance at the minimum is however higher than for
                      homogeneous surfaces. Furthermore, the potential at the
                      minimum deviates significantly from the potential of zero
                      mean charge on the surface if l>3d(Debye) and Delta phi(pzc)
                      is larger than about 4k(B)T/e. The capacitance of stepped,
                      partially reconstructed Au(11n) surfaces is discussed as an
                      example. Consequences for Parsons-Zobel-plots of the
                      capacitances of inhomogeneous surfaces are likewise
                      discussed. (C) 2010 Elsevier B.V. All rights reserved.},
