Abstract

A new equation for calculating the number of atoms in a critical nanocluster, which is suitable for the case of metal electrocrystallization, is derived. The equation takes into account the Tolman size factor (the dependence of specific surface energy on the cluster size) and/or the surface energy gradient, that is, the effect of subsurface atomic layers. At small overvoltages, the equation takes the classical form.
