Abstract
The hole transport in polystyrene doped with 15 wt % tritolylamine is studied via the time-of-flight technique in both the surface carrier generation mode and the bulk carrier generation mode. The hole transport is shown to be dispersive with a dispersion parameter value of 0.99 ± 0.03 at room temperature. The results contradict the widely held view that hole transport in this molecularly doped polymer is quasi-equilibrium. The hole mobility is found to be almost independent of the electric-field intensity.
