Abstract
We report on the analysis of step fluctuations on a Cu (100) electrode in a queous electrolyte. From the time dependence of the fluctuations we determi ne the mass transport involved in the fluctuations as a function of the ele ctrode potential. We obtain a value for the total activation energy of the relevant mass transport. The results are compared to those for Ag electrode s and we give a value for the kink energy on silver in a Cu2+ containing el ectrolyte. The problem of a possible tip influence on the step fluctuations is also addressed. (C) 1999 Elsevier Science Ltd. All rights reserved.
