Unique Constant Phase Element Behavior of the Electrolyte–Graphene Interface

Nanomaterials, 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.

Analytical–Computational Integration of Equivalent Circuit Modeling, Hybrid Optimization, and Statistical Validation for Electrochemical Impedance Spectroscopy

Electrochem
Background: Electrochemical impedance spectroscopy (EIS) is indispensable for disentangling charge-transfer, capacitive, and diffusive phenomena, yet reproducible parameter estimation and objective model selection remain unsettled.
