Studies in electrocrystallization: Part III. The effect of ohmic and finite risetime distortions on data acquisition in 2D nucleation and growth

Abstract

The effect of uncompensated iR-drop on two-dimensional nucleation and growth is described. Both instantaneous and progressive nucleation laws are considered. Also the effect of the finite risetime of potential square-waves on the experimental data acquisition is presented. Data are examined in terms of current-time transients and also in terms of the transient maximum parameters i m and t m. It is demonstrated that neglect of ohmic and finite risetime factors causes complex distortions of rate data, particularly at short times. Prospects of minimising these distortions are briefly considered.
