The Role Played by Migration and Diffusion on the Morphology of 3D Silver Electrodeposits |

|---|---|---|
Spherical 3D silver dendritic electrodeposits were grown at constant potential (E(d)) covering the -0.3 V less than or equal to E(d) less than or equal to 0.1 V range in 0.50 M Na2SO4 + 0.010 M H2SO4 + 5x10(-3) M Ag2SO4 and in 5x10(-3) M Ag2SO4 + 2x10(-5) M H2SO4 The Solution was gellified with Agarose to avoid free convection. In the -0.3 V less than or equal to E(d) less than or equal to 0.1 V range the following relationship between Q, the silver electrodeposited charge and R, the radius of gyration of the growing object, was obtained, Q proportional to R(DM) with D-M, the mass fractal dimension equal to 2.5+/-0.1. Otherwise, in the -0.3 V less than or equal to E(d) less than or equal to 0.1 V range the radial growth velocity increased as E(d) decreased. The decrease in the concentration of the supporting electrolyte in the gellified medium resulted in dense branched silver electrodeposits with D-M = 3.0+/-0.1. These results demonstrate the influence of diffusion and migration contribution on the development of either DLA or dense radial patterns in metal electrodeposition. |
