Jonscher regime

The exponent value of 0.6 in Jonscher regime is considered to arise by the ion-ion interactions, usually of the coulombic type. During the process of the hopping of the ions, even separate hopping events may have a broad distribution of relaxation times, and this effect can manifest as stretching of the relaxation times. Ngai s coupling model accounts for stretched exponential relaxation and considers it as a consequence of... 

Extracting the dc Conductivity. There are several ways to extract a value of the dc conductivity from impedance spectroscopy data. A method that is built on the amply documented power-law response at frequencies above the dc regime (Jonscher [1983]) is presented here. If we assume that cr has an approximate power-law behavior within some frequency range, it can be expressed as...
