Impedance of constant phase element (CPE)-blocked diffusion in film electrodes

Journal of Electroanalytical Chemistry, 1998
Abstract We construct a model of ac impedance response to blocked linear diffusion that has a sloped low frequency region in the impedance plot. The approach is based on the transmission line analogy to linear diffusion, and it is equivalent to solving Fick’s law with a boundary condition that allows us to set an arbitrary impedance response at low ...

Contribution of Surface Roughness to Constant-Phase Element (CPE) Behavior

ECS Meeting Abstracts, 2015
While CPEs are commonly used to improve the fit to experimental impedance spectra, the explanation for their origin has been largely conjectural.  In early experiments on solid electrodes, micro-scale surface roughness was believed to contribute to the non-ideality of electrochemical measurements.1 Borisova and Ershler were the first to

Concerning the use of constant phase elements (CPEs) in the analysis of impedance data

Materials and Corrosion, 2010
AbstractImpedance spectra obtained for Al6061 samples that had been anodized and sealed in two different processes and subjected to thermal cycling at three different temperatures have been analyzed using the Equivcrt software using a three‐time constant model with four constant phase elements (CPEs).

Constant-phase-element (CPE) modeling of ferroelectric random-access memory lead zirconate-titanate (PZT) capacitors

Journal of Applied Physics, 2007
Several commercial high density ferroelectric random access memory (FeRAM) devices utilize stacks of submicron lead zirconate-titanate (PZT) capacitors. The low-field electrical characteristics of these capacitors display a specific frequency dependence which is best represented by a constant phase element (CPE) in the equivalent circuit diagram.

Constant-Phase-Element Behavior Caused by Resistivity Distributions in Films

Journal of The Electrochemical Society, 2010
CPE behavior may be attributed to the distribution of physical properties in films, in the direction normal to the electrode surface. Numerical simulations were used to show that, under assumption that the dielectric constant is independent of position, a normal power-law distribution of local resistivity is consistent with the Constant-Phase Element ...
