Abstract :We have investigated transient changes in surface morphologies of Ag-Sb electrodeposits. Microscopic images of the Ag-Sb electrodeposits reveal that the surface morphology comprising Sb-poor and Sb-rich Ag deposits are described by a scaling function that is characterized by scaling exponents related to the growth mechanism of the Ag and Sb coelectrodeposition. The values of the scaling exponents indicate that Sb atoms which arrive at electrodes diffuse only in a local area. On the basis of a scenario that perturbations of ion concentrations in the electrolyte caused by Sb electrodeposition develop with time, a condition for the transient changes in the surface morphology is derived using linearized perturbation equations of the rate equations. The experimental results qualitatively support the instability condition.
