A SIMPLE MODEL OF ac HOPPING CONDUCTIVITY
The physics of ac hopping conduc2ivity in disordered solids is discussed in the light of a recently proposed model. Several new comments are made. One of the most interesting facts about conductivity in disordered solids is the surprising similarity between ionic and electronic conductivity. The same kinds of non-linearities in strong electric fields are observed, and ionic and electronic condu...
متن کاملA Simple Model of Ac H O P P I N G Conductivity in Disordered Solids
Using the CTRW approximation the simplest possible nontrivial model of ac hopping conductivity in disordered solids, is constructed. The model predicts universality of the frequency-dependent conductivity, independent of temperature, chemical composition, and conductivity mechanism, in reasonably good agreement with experiments. It is shown that all qualitative features of experimental ac hoppi...
متن کاملSimple model for ac ionic conduction in solids.
We present a model for the ac conduction in ionically conducting solids that takes into account, in a simple way, the interaction between carriers. The Coulomb force forms an "ionic atmosphere" that exerts a restoring force on a central ion, whose motion corresponds to an overdamped oscillator. We consider the effect of the relaxation of the ionic atmosphere by introducing an additional equatio...

متن کاملConductivity in Two-Dimensional Disordered Model with Anisotropic Long-Range Hopping
Abstract We consider two-dimensional system of particles localized on randomly distributed sites of squared lattice with anisotropic transfer matrix elements between localized sites. By summing of ”diffusion ladder” and ”cooperon ladder” type vertices we calculated the conductivity for various sites and particles densities. The model is relevant to the problem of strong nonmagnetic impurities i...
