Abstract
An external (d.c.) electric field, applied across a metal/liquid interface, can shift the electronic levels of the metal surface. If not resolved properly, this effect can be problematic in voltage controlled surface studies, particularly in spectroscopy where photon induced interband transitions are active. A simple method, based on surface charge measurements by differential capacitance technique, is presented to account for such energy shifts. The technique is applied to estimate voltage induced shifts in the d-Fermi level transition threshold in the surface layer of a polycrystalline Cu electrode. The results are in striking agreement with those indicated by previously reported optical experiments on Cu.
