Transient Photoconductivity and Dark Conductivity in Discotic Liquid Crystals

Abstract
A comparative study of transient photoconductivity and dark conductivity in the discotic liquid crystal hexahexyloxytriphenylene (HAT6) is reported. In both experiments the transport is dispersive, and the carrier mobilities are essentially identical demonstrating that the presence of the counterions in the chemically doped conductors does not significantly perturb the mobility.
