Hole Transport and Biomolecular Recombination of Charge Carriers in Polycarbonate Molecularly Doped with Aromatic Hydrazone

Polymer Science - Series A. 2014. Vol. 56. No. 2. P. 152-157.

Abstract—General questions about hole transport and bimolecular recombination of charge carriers in molecularly doped polycarbonate with a low dopant concentration (10 wt %) are considered. The experiment is performed via a radiation-induced time-of-flight technique with bulk generation of charge carriers. Transient-current curves are calculated numerically via a multiple-trapping model. There is good agreement between the calculated and experimental results on the transient-current waveform. Nonequilibrium hole transport is observed in the studied molecularly doped polymer, and the bimolecular recombination is close to the Langevin recombination as described by the multiple-trapping model.
