Abstract

We introduce an aggregation model for general electrochemical deposition experiments. Its most relevant feature is that it includes the overall effect of strong applied electric fields and therefore applies to non-equilibrium situations. We compare our model to experiments on CoP dendritic growth with very good agreement: The model accurately reproduces the dependence on the current of the alloy's composition, morphology, and growth time.
