Abstract

The superposition of Debye-like relaxation processes with different relaxation times, τ = τ0·exp(W/kBT), has a 2D-distribution, G(W, 1n τ0) of activation energy, W, and pre-exponential factor, τ0. With a novel method we evaluate G via inversion of temperature dependent broadband dielectric data. Simulations as well as experimental data demonstrate the validity of the analysis.
