Electrodeposition of Fe, Pt and Fe–Pt on n-type Si (001) wafer was studied. The electrochemical
nucleation and growth mechanism was investigated using conventional electrochemical techniques and morphological
examinations. The current transients recorded during potentiostatic deposition were compared
with the non-dimensional plots predicted by the Scharifker-Hills theory indicating that there exists a progressive
nucleation mechanism for the electrodeposition of iron and platinum on the silicon substrate. Using
different methods it was shown that the diffusion coefficient of iron ions is about three times larger than that
of platinum ions. All single and multi-component system studied reveal 3D multiple nucleation with diffusion
controlled growth.
