Abstract

We have shown that the use of blocking electrodes results in a spectrum of effective relaxation times, which considerably differs from the intrinsic one characterising the dynamics of bulk material. An effective medium analysis allows us to transform the effective distribution into the intrinsic one and vice versa. The procedure can be applied to data obtained by dielectric relaxation spectroscopy as well as to TSDC data
