Abstract

Charge transport in poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] is studied by employing the time-of-flight technique. Film morphology plays a key role in determining the charge transport properties. Samples prepared from toluene feature non-dispersive transport. However, after thermal annealing, charge transport is no longer nondispersive and hole mobility drops for about one order of magnitude. Near-field scanning optical microscope images show that annealing enhanced film inhomogeneity. We propose that the inhomogeneity is responsible for the changes in the transport properties.
