Analysis of ion diffusion and charging in electronically conducting polydicarbazole films by impedance methods

Electrochemical impedance analysis of the redox switching hysteresis of poly(3,4-ethylenedioxythiophene) films

“…The electrochemical impedance response of electronically conducting polymers is known to be represented by a circuit model containing interfacial as well as diffusion elements in cases where the polymer films are regarded as homogenous [14,15]. In the simplest configuration, slow mobile charge carriers (i.e.…”

Structural and electrochemical characterization of carbon electrode modified by multi-walled carbon nanotubes and surfactant

“…7) which is generally expressed with the transmission line model was employed to represent the impedance response of the diffusion process. This model has been used to analyze different systems where the charge transfer is controlled by a diffusion mechanism [40][41][42]. According to Fig.…”

Organohalide Perovskites are Fast Ionic Conductors

“…[14] Diffusion impedances undergo a pattern change at a certain characteristic frequency d ω at which a transition between a Warburg-to a capacitivelike behavior is observed. [20,21] The frequency d ω is located near the elbow of the impedance plot, as marked in Figure 2b, and relates to the chemical diffusion…”
