of the reduction current on potential. The current dip after the passivation peak is due
to the reduction of ferricyanide through the thin oxide film, the rate of which decreases
to zero as the film thickness increases at more positive potentials.
The reduction of in solutions, in contrast to that in KOH solu-
tions, does not proceed on p -Si in the dark indicating that the reduction can only proceed
with conduction band electrons. 986 However, the presence of defects such as disloca-
