Influence of additives on deposition at different crystallographic faces

2 Influence of additives on deposition at different crystallographic faces 

The rate of the crystallization process of a pure metal differs for different crystallographic faces. For comparison, the net deposition current density can be split into partial current densities L 

The growth rate, characterized by the partial current density is the factor determining the equilibrium shape of a crystal. The faces with the smallest partial current densities 

Additives can control the growth rate by blocking surface processes, e.g., surface diffusion or the transfer in and out of kink site positions. Therefore, interaction of additives with the different crystallographic structures is a dominating factor in the development of crystallographic shape and structure.
