Electrochemical nucleation and growth of three-dimensional clusters: the case of multi-step ion discharge-II

Electrochemical nucleation and growth of three-dimensional spherical clusters on a foreign substrate are considered in case of multi- and single-step ions discharge reaction. Theoretical expressions are derived for the stationary nucleation rate and for the current-time and the radius-time relationships of single clusters growing at a constant electrochemical supersaturation. The error that would be made if the important physical quantities critical nucleus size and exchange current density are determined not using correct theoretical formulas accounting for the actual multi- or single-step reaction mechanism is evaluated.
