Abstract

Silver films were electrodeposited onto gold substrates mounted on a rotating disc electrode. The effects of rotation speed and current density on the conventional and fractal analyses of the films were studied. Conventional processing indicates that grain size and the RMS roughness decrease as the rotation speed of substrate increases. The fractal analysis suggests that the fractal dimension can be used to explain the variation of the entire grain morphology along direction of the growth. Moreover, results show that the samples electrodeposited at higher current densities are much rougher (and have bigger grain sizes) than those grown at lower current densities. Also, the results show that the increasing substrate rotation speed has the same effect as decrease of deposition current density on the conventional parameters of the silver films.
