SURFACE SMOOTHING OF COPPER SINGLE-CRYSTALS USING POM (POTENTIAL OSCILLATING METHOD)

The deposition of metals is a process to get metallic coatings on meta ls. The potential oscillating method (POM) allows dissolution and depo sition processes in parallel. Using this method the crystal's habit be comes more perfect, and the equilibrium form can be obtained. It is mo stly dominated by the {111}- and the {100}-face, as usual for cubic fa ce centered crystals. The crystallographic faces develop more clearly and become smoother. This paper deals with the determination of the id eal conditions for the electrochemical experiment using copper single crystals, and the analysis of the surface topography using light micro scopy, and scanning force microscopy.
