Results

We run program on the lattice 7x7x7. The next graph demonstrates histogram of site energy deviation. You can see that energy deviates not so fine as we expected.

Much attention has been paid in recent years to the dependence of the mobility on electric field. The drift mobility of carriers in organic disordered media in experiment usually demonstrates exponential dependence on electric field in the form of [1]:

So, we have expected from our simulation such sort of dependence of mobility from the external field. The obtained in simulation results we present on the next graphs:

Fig.2 The logarithm of the mobility versus E^1/2

We can see that dependence mu(E^1/2) is more complex then exponential. For the purpose to compare our results we presents simulation results that were obtained by P.M. Borsenberger, L. Pautmeier, H. Bessler[4]:

There are some similarities in the behavior of mu (E^1/2)-dependence, but there are some differences that we can try to explain.

The most possible reason is that we run program on relatively small lattice and small number of jumps
Also we did not average result by different energetic configurations (by the different seeds)
It is not clearly understood what is arbitrary units of mobility that we see on the graphs (Fig.3). May be we have to renormalize your results.

Further development

It is obvious necessity to generate large extended along field lattices
It is also needed to change random number generator to more sophisticated
It have to be spent more time for investigation behavior of mu (E^1/2)-curve in different energetic configurations
It would be convenient to develop program to the version that gives away data in the graphic presentation. For example, we could use PGPLOT graphical subroutine library for this purpose.
