| Abstract Scope |
Electrodeposition of metals has been long studied1 given the industrial and scientific relevance. Local depletion of cationic concentration1-3 has been widely recognized as the condition for the onset of irregular growth (equivalent to a limiting current). Such a signature, however, does not offer any insights into the local structure, for example, growth modes commonly recognized in solidification4,5. Present work analyzes electrodeposition as a front propagation problem. Short time dynamics is investigated to identify the unstable lengths. Furthermore, long-time dynamics is studied to elucidate growth structure. Complicating features like interfacial energy, nucleation sites, reaction kinetics are also discussed to isolate universality in electrodeposition growth.
