Impedance Spectroscopy of Spin‐Cast and Electrochemically Deposited PEDOT:PSS Films on Microfabricated Electrodes with Various Areas

Film cast: Electrochemical impedance spectroscopy is used to characterize the charge-transport properties of both spin-cast and electrochemically deposited PEDOT films on a series of designed electrodes with systematic variations in size. The spectra are analyzed in terms of a two-element equivalent circuit model with a solution resistance Rs and film capacitance C. By normalizing the impedance with respect to Rs (Zn=|Z|/Rs) and the frequency with respect to fc (fn=f/fc), all of the experimental Bode curves can be collapsed into a single master plot of Zn versus fn.
