The Microworld of Electrodeposition

Part of the NATO ASI Series book series (volume 167)


The diffusion limited aggregation (DLA) model by Witten and Sander1 has been widely used to decribe ramified pattern formation in processes like particle aggregation, viscous fingering, dielectric breakdown and electrodeposition (ED). The purpose of this presentation2 is to show a wide range of growth morphologies in ED for silver and tin. The results are similar to earlier ED-experiments3,4,5 but certain aspects are visualized for the first time.
