Abstract

The interfacial impedance of polycrystalline solid electrodes in the absence of Faradaic reactions is never purely capacitive, the deviation from ideal capacitive behavior is usually larger on rough electrodes than on smooth ones. Qualitative experiments to demonstrate that the frequency dependence of capacitance on solid electrodes is due to the atomic scale inhomogeneities rather than to the geometry aspect of roughness.
