Electrodeposition of copper on a copper single crystal (100) face and on a copper polycrystalline surface in the presence of sulfaguanidine

In the presence of sulfaguanidine, a triangular pyramid growth form changes successively to a layer type of growth which transforms to ridges and then to a polycryst. deposit on a (100) single-​crystal Cu substrate. On a polycryst. Cu surface the grain size of the deposit is affected markedly by sulfaguanidine. The change in the growth form and overvoltage are explained with the help of IR and x-​ray techniques
