Current transient recorded at −0.34 V overpotential on an ITO electrode in 1.0 × 10−3 mol dm−3 CuSO4(aq). AFM images recorded ex-situ after 0 (ITO topography), 15, 30 and 60 s are superimposed in the figure. Statistical analysis of a number of electrodes resulted in a constant nuclei number density of (1.5 ± 0.8)× 108 cm−2, which is consistent with an instantaneous nucleation mechanism
