Charge surface nuclei growth

Mononucleation Mononucleation events at electrochemical interfaces have been observed in potential step experiments by monitoring current, charge, or capacitance as a function of time under conditions of (1) low supersaturation and (2) small, defect-free electrode surfaces. These experiments offer the unique opportunity to determine simultaneously absolute rates of the nucleation and growth processes. The formation of the critical nucleus appears stochastically in time and space (Fig. 3). The time distribution (continuous) of the birth events of critical nuclei (discrete), as indicated by the onset of the subsequent growth transient (current/charge increase, decrease of interfacial capacitance), within a sufficient long train of repetitive transient experiments under identical conditions, leads...
