Abstract
The relation between layer properties and structure of the deposit is of permanent importance in the development of electrocrystallization. The continuous question is the influence of the experimental conditions on the structure and with this bridge on the properties of electrodeposits. A very important step in electrodeposition is nucleation. Some recent developments of nucleation will be discussed. An important factor to influence nucleation and growths are additives. Adsorption of additives is still described by the thermodynamic approach of adsorption isotherms. But a new impetus might provide the transfer of Pearson's hard–soft concept to adsorption on electrified interfaces. An important step is the correlation of hardness and softness with the chemical potential of electrons and the dependence of the chemical potential on the electrode potential. A further new step is the application of distributed field calculations to calculate chemical potentials of electrons. An outlook into further developments is given at the end of the article.
