Abstract

The common technique of dielectric ε *(co) or ε(t) measurements involves the application of a polarization invariant electric field to a capacitor filled with the material under study and the detection of the temporal evolution of the resulting current or charge flow. The counterpart condition of applying a given dielectric displacement and monitoring the electric field relates to the dielectric modulus M(t) with M *(ω) = 1/ε *(ω). Isothermal and thermally stimulated experimental techniques for directly accessing the relaxation M(t) are outlined and discussed as regards their relation to the dielectric retardation ε(t) and to dc-conductivity σ dc. We also address several microscopic processes which are inherently linked to the dielectric modulus through their common feature of displaying a redistribution of charge.
