Abstract—A multiple-trapping model has been used to numerically analyze the effects of the nonequilibrium
transport of holes on the field dependence of drift mobility as obtained in a time-of-flight experiment. The
intrinsic field dependence has been assigned to the frequency factor in the form of the Poole–Frenkel law.
Strongly dispersive transport, as well as a nonequilibrium-charge-transfer regime given by the Gaussian disor-
der model, has been considered. It has been established that the currently accepted approach to the analysis of
the field dependence of mobility needs to be reexamined.
