摘要

We present a model to describe electrical transport in disordered materials. Solving the rate equation by the Green function technique and taking into account the electric field effect on the effective dimension of the transport path, we obtain a different law for the conductivity field dependence. This law could be confounded with the Poole-Frenkel law in the range of field, corresponding to the experimental observations in organic materials and conjugated polymers. We show that this behavior is a common feature of all disordered systems. We find a field-induced crossover on the temperature dependence of the conductivity.
