The Role Played by a Polymer Matrix in the Transfer of Charge Carriers in Molecularly Doped Polumers

Russian Journal of Physical Chemistry B. 2012. Vol. 6. No. 2. P. 315-320.

Transient current curves were recorded for polystyrene and polycarbonate doped with 15 wt % tritolylamine using both surface and volume charge carrier generation. The multiple trapping model was used to perform numerical calculations of time-of-flight curves for the published Gaussian disorder model parameters. The calculation results were compared with the experimental data. It was shown that the experimental and calculated curves satisfactorily coincided. The flat plateau observed in time-of-flight curves should not be associated with the establishment of a  quasi-equilibrium transport regime.
