Dielectric relaxation in solids
TL;DR: In this paper, a broad-brush view of dielectric relaxation in solids is presented, making use of the existence of a universality of Dielectric response regardless of a wide diversity of materials and structures with dipolar as well as charge-carrier polarization.

On the Dispersion of Resistivity and Dielectric Constant of Some Semiconductors at Audiofrequencies
TL;DR: In this paper, the ac resistivity and the apparent dielectric constant of the material show a dispersion which can be explained satisfactorily with the help of a simple model of the solid: there should be wellconducting grains separated by layers of lower conductivity.

Electroceramics: Characterization by Impedance Spectroscopy
TL;DR: In this paper, the authors used impedance spectroscopy for unravelling the complexities of such materials, which functions by utilizing the different frequency dependences of the constituent components for their separation, and showed that electrical inhomogeneities in ceramic electrolytes, electrode/electrolyte interfaces, surface layers on glasses, ferroelectricity, positive temperature coefficient of resistance behavior and even ferrimagnetism can all be probed, successfully.
