Dielectric relaxation in solids
TLDR
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.Abstract:
This review presents a wide-ranging broad-brush picture of dielectric relaxation in solids, 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. The review of the experimental evidence includes extreme examples of highly conducting materials showing strongly dispersive behaviour, low-loss materials with a `flat', frequency-independent susceptibility, dipolar loss peaks etc. The surprising conclusion is that despite the evident complexity of the relaxation processes certain very simple relations prevail and this leads to a better insight into the nature of these processes.read more

A.c. conduction in amorphous chalcogenide and pnictide semiconductors
TL;DR: In this article, a comprehensive survey is given of the experimental a.c. data for two types of amorphous semiconductor, namely chalcogenide and pnictide materials, and it is concluded that the behavior at intermediate to high temperatures is well accounted for by the correlated-barrier-hopping model, whereas the low-temperature behaviour is probably due to atomic tunnelling.

Polymer nanocomposite dielectrics-the role of the interface
TL;DR: In this paper, the incorporation of silica nanoparticles into polyethylene increased the breakdown strength and voltage endurance significantly compared to the inclusion of micron scale fillers, and showed a decrease in dielectric permittivity for the nanocomposite over the base polymer.

The realization of the generalized transfer equation in a medium with fractal geometry
TL;DR: In this article, it is shown that in a medium representing an example of "Koch's tree" type fractional structure the diffusion process is described by a generalized transfer equation in partial derivations.

The ‘universal’ dielectric response
TL;DR: A review of dielectric data for a wide range of solids proves the existence of a remarkable "universality" of frequency and time responses which is essentially incompatible with the multiplicity of currently accepted detailed interpretations as discussed by the authors.

The universal dielectric response
TL;DR: In this article, a brief description is given of the various manifestations of the universal fractional power law relaxation processes, which are contrasted with the classical or Debye law, and a novel very general approach based on the so-called energy criterion is introduced.

Low-Frequency Conductivity Due to Hopping Processes in Silicon
TL;DR: In this paper, a simple theory based on the currently accepted model of impurity conduction is given for the higher temperature range, which accounts well for the observed frequency and concentration dependences, but only order-of-magnitude absolute agreement is obtained.

A cluster approach to the structure of imperfect materials and their relaxation spectroscopy
L.A. Dissado,R. M. Hill +1 more
TL;DR: In this article, a new theory is proposed for the explanation of observed relaxation phenomena, which differs significantly from theories suggested by the authors before, and is based on a model of structural organization of macroscopically sized samples of imperfectly structured materials, both solids and liquids.
