Carrier density, substrate and synthesis temperature dependent impedance measurements have been performed on Poly(3,4-ethylenedioxythiophene) PEDOT] based devices in metal/polymer/metal geometry at room temperature. The relaxation mechanism of carries in these devices can be varied as per the growth condition. It is observed that in stainless steel (SS)/PEDOT/Silver (Ag) devices, as the carrier density decreases the interface related mechanism takes control over bulk transport, but as the synthesis temperature is lowered the bulk transport dominates over interface related mechanism. The substrate dependent studies have shown that the electrode potential can alter the growth of polymer chains, which affects the relaxation mechanism of the carriers.
