Electrochemical impedance spectroscopy (EIS) results are shown and interpreted with regard to other recent experimental studies for copper deposition in the presence of polyethylene glycol and . The model assumes the adsorption of a nearly complete monolayer of PEG in the presence of chloride ions and no adsorption without . The primary effect of PEG adsorption which does not appear to vary with time during an EIS measurement, is a blocking of available surface sites for charge transfer. The model effectively predicts changes in steady‐state and EIS results with changes in concentration and rotation rate on a rotating disk electrode.
