  We present the results of Monte-Carlo simulations of the charge carrier
transport in a disordered molecular system containing spatial and energetic
disorders using the dipolar glass model. Model parameters of the material were
chosen to fit a typical polar organic photoconductor polycarbonate doped with
30% of aromatic hydrazone, whose transport properties are well documented in
literature. Simulated carrier mobility demonstrates a usual Poole-Frenkel field
dependence and its slope is very close to the experimental value without using
any adjustable parameter. At room temperature transients are universal with
respect to the electric field and transport layer thickness. At the same time,
carrier mobility does not depend on the layer thickness and transients develop
a well-defined plateau where the current does not depend on time, thus
demonstrating a non-dispersive transport regime. Tails of the transients decay
as power law with the exponent close to -2. This particular feature indicates
that transients are close to the boundary between dispersive and non-dispersive
transport regimes. Shapes of the simulated transients are in very good
agreement with the experimental ones. In summary, we provide a first
verification of a self-consistency of the dipolar glass transport model, where
major transport parameters, extracted from the experimental transport data, are
then used in the transport simulation, and the resulting mobility field
dependence and transients are in very good agreement with the initial
experimental data.
