Chemical interface damping (CID) is a change of the effective collision frequency of electrons in metal due to chemical change of the metal interface. We show that electrochemical oxidation of gold leads to CID effect. The increase in collision frequency is determined by in-situ ellipsometric measurements during oxidation of flat single crystal and polycrystalline gold films.
