Monte Carlo simulation of hopping transport in dipolar disordered organic matrices

We present results of the Monte Carlo simulation of charge carrier transport in a simple model of randomly oriented and orientationally noncorrelated dipoles and compare our results with those obtained for standard Gaussian disorder model. The most significant difference is a shift of the Pool-Frenkel region of the mobility field dependence to lower fields and widening of this region. We have found that in some particular cases the mean carrier velocity is a decreasing function of the electric field.
