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 ...

An unreasonably large pre-exponential factor for conductivity is an old problem with interpretations of hopping transport data on a-Si and a-Ge. It is shown that an appropriate concave density of states eliminates this problem, and explains some other experimental features. Results of a percolation...
By using a combination of detailed experimental studies and simple theoretical arguments, we identify a novel mechanism characterizing the hopping transport in the Mott insulating phase of Ca$_{2-x}$Sr$_x$RuO$_4$ near the metal-insulator transition. The hopping exponent $\alpha$ shows a system...

Computer simulations for trap-controlled transport show that mobility, estimated from the time of intersection of the asymptotes to plateau and trailing edge of photocurrent transient, is very sensitive to the variation of transient shape and, in some cases, effectively masquerades the real ...

Transport theoryWe have tried to look systematically at all the assumptions and concepts that appear in hopping theory explicitly or implicitly. The guiding idea we followed was that about markovian processes, described by a Master equation, as well as a detailed analysis of the assumptions of the...
