Unique Constant Phase Element Behavior of the Electrolyte–Graphene Interface [PDF]

open access: yesNanomaterials, 2019
We report a unique constant phase element (CPE) behavior ( 1 Z = Q 0 ( j ω ) α ) of the electrolyte−graphene interface with both Q 0 and α showing dependence on the gate voltage.

Difference between Charge–Voltage Relations of Ordinary and Fractional Capacitors

open access: yesFractal and Fractional, 2023
In an ordinary time-varying capacitor, there is debate on whether a time-domain multiplication or a time-domain convolution of capacitance and voltage determines charge.

Revealing the role of the constant phase element in relaxor ferroelectrics

open access: yesCommunications Physics, 2022
Relaxor ferroelectrics are a type of material exhibiting electrostriction whereby a change in the material shape occurs under an applied electric field; however, although known by the community for many years the underlying mechanisms of the phenomenon ...
