Compensation between the parameters of the Jonschers's Universal Dielectric Response Law in disordered materials

Anthony N. Papathanassiou, Elias Sakellis

Experimental results for a huge number of different materials published during the past fifty years confirm the validity of the Jonscher's Universal Dielectric Response Law. Accord…

Correlation of the scaling exponent of the diffusivity-density function in viscous liquids with their elastic properties

Anthony N. Papathanassiou, Ilias Sakellis

Fundamental thermodynamical concepts and a solid-state point defect elastic model are used to formulate a diffusivity-density scaling function for viscous liquids. It is proved in…

Effect of composition on the dielectric relaxation of zeolite-conducting polyaniline blends

I. Sakellis, A. N. Papathanassiou, J. Grammatikakis

The complex permittivity of conducting polyaniline and zeolite - polyaniline blends was measured in the frequency range 0.01 to 2000000 Hz from room temperature to liquid nitrogen…

Transformation of polarons to bipolarons in disordered matter

I. Sakellis, A. N. Papathanassiou, J. Grammatikakis

The polaron to bipolaron transition in disordered media under the influence of a broadband ac electric field is suggested: ac conductivity vs. frequency measurements in disordered…

Migration volume for polaron dielectric relaxation in disordered materials

A. N. Papathanassiou, I. Sakellis, J. Grammatikakis

A theoretical study of the influence of pressure on the dielectric relaxation related with polaron tunneling and phonon assisted hopping in disordered solids is developed. The sign…

Universal frequency-dependent ac conductivity of conducting polymer networks

A. N. Papathanassiou, I. Sakellis, J. Grammatikakis

A model based on the aspect of the distribution of the length of conduction paths accessible for electric charge flow reproduces the universal power-law dispersive ac conductivity…
