I would like to study about the Debye relaxation and cole-cole plot.

Manohar Sehgal

1) Thermal behaviour follow the relation:

τ =τo ⋅ e^W0/ kBT

Certainly, this results in an exponential dependance of the relaxation frequency with temperature

2) Cole – Cole diagram

In case of true Debye behavior(only one relaxation time)plotting imaginary against real part forms a semi-circle.

For diagram:

Cole-Cole-Diagramm(Wikipedia).
