For understanding the choice of the electrode potential for nucleation and growth
pulses, the schematic voltammograms in Fig. 10.6 are shown as a guide. When a
potential scan is run to the negative direction, the current on HOPG is practically
Fig. 10.6 Schematic graph of a cyclic voltammogram for metal nucleation and deposition on
HOPG. Arrows indicate the scan direction. Solid and dashed lines in the anodic-going scan indicate
the absence and presence of the oxidation of absorbed hydrogen. Potential intervals: N—nucleation,
G—growth. S stands for the stripping peak of the deposit. Current ratios strongly depend on both
the sweep rate and the cathodic limit of the sweep. Sketched after Refs. [21, 23, 24, 28, 29]
