Abstract

We present a study of transport in various disordered systems based on three different formalisms. We focus on the questions of diffusion of excitations and charge carriers in homogeneously disordered systems and on the conductivity in inhomogeneous (granular) systems. We derive first the generalized master equation as the basic equation for transport in a disordered system and then relate it to the continuous time random walk formalism and to the effective medium approximation approach. In the inhomogeneous case we use the critical path method to calculate the temperature dependence of the d.c. conductivity.
