ABSTRACT
The scope of impedance spectroscopy (IS) measurements has been extended to broader areas of research continuously during the last decades. Originally, the method was mainly used to characterize liquid phase electrochemical cells, but its power to characterize resistive and capacitive properties of solid matter has been exploited more frequently ever since.1 The analysis and equivalent circuit modeling of IS data obtained from macroscopic bulk materials are performed routinely and are well understood these days.2,3 On the other hand, the application of IS to nanomaterials has become increasingly popular only recently, where the main aspiration is to achieve local impedance characterization on small length scales down to the nanoscale.
