Local concentration measurements in electrochemical deposition using a schlieren method

Abstract

We report local concentration measurements of electrolyte in electrochemical deposition using a schlieren method. The intensity contrast of schlieren images is used to obtain concentration information. The images reveal active regions of the growth and thus provide excellent records to study the dynamics of electrochemical deposition processes. Quantitative results of local concentration measurements in the early stages of the growth agree well with recent model calculations.
