abstract = {The influence of the first stages of anodic oxidation of
p-Si on the mechanism of Co deposition was studied by means
of electrochemical techniques and AFM. The surface
transformation during the formation of a thin oxide layer on
hydrogen-terminated Si was followed by capacitance
measurements and related to changes of the electrodeposition
mechanism. It was observed that the reduction of Co2+ on
oxide free p-Si occurs at the negative side of the flat band
potential involving the discharge of photogenerated
electrons at the conduction band edge and/or surface state
levels. The fort-nation of an oxide film of d(ox) < 2 nm
introduces an energy barrier that increases the
overpotential for electrodeposition. The morphology of
deposits, on the other hand, changes from layer like to
grain like after surface oxidation, indicating a substantial
modification of the nature and density of nucleation sites.
The number density of deposited clusters on an oxidized
surface showed a proportionality with the field strength in
the oxide, indicating the presence of a certain high-field
assisted mechanism in the generation of active sites. (c)
