Studies on the Electrochemical Growth of (Per)<sub>2</sub>[Au(mnt)<sub>2</sub>]
The first stages of the electrocrystallization of (Per)<sub>2</sub>[AuĀ(mnt)<sub>2</sub>] salt from dichloromethane on gold, platinum,
and highly orientated pyrolytic graphite (HOPG) were investigated
by cyclic voltammetry, atomic force microscopy, and X-ray photoelectron
spectroscopy in order to understand the determinant factors for nucleation
and crystal growth. The crystal growth occurs from adsorbed films
of dithiolate on gold or platinum and of perylene on HOPG, after homogeneous
nucleation, and it is controlled by the low diffusion of the species
toward the growing surface
