Preparation of dendritic tin nanoaggregates by electrodeposition

We have used a new galvanic technique to obtain tin nanoaggregates on an insulating surface. This study describes the morphology and the size of these nanoaggregates and the operating parameters. The nanoaggregates show a dendritic structure composed of polycrystalline grains with grain size down to 20 nm. The microstructural characterization has been achieved by scanning and atomic force microscopes. Potential curves allow one to describe the onset of nucleation.
