On the intrinsic electrochemical nature of the inductance in EIS. A Monte Carlo simulation of the two-consecutive-step mechanism: The flat surface 2 D case

Much has been argued about the inductances in electrochemical impedance spectroscopy (EIS), which are recurrently ascribed to electrochemical or non-electrochemical events and even experimental artifacts. In the present paper, computational microscopic simulations of metallic dissolution based on the microscopic Monte Carlo algorithm allowed the effect of surface adsorbate relaxation to be isolated from other possible intervening features such as surface relaxation. Results have unambiguously shown that surface adsorbate relaxation can effectively yield inductive loops as predicted by the classical macroscopic description of the metal-electrolyte interface by kinetic equations.
