Time of flight analysis of charge transport in insulators for the nondispersive trap limited domain

Abstract

We consider the unipolar carrier transport problem through an insulating media with traps. The charge packet drifts under the influence of an external electric field applied between two electrodes. We solve the Poisson equation exactly and find the electric field distribution in the device. The displacement current on the electrodes is obtained for the case of a non-dispersive thin charge packet, with deep trapping characterized by a single time constant τ. A generalization of the induced charge “splitting theorem” in such devices is obtained for the trapping case.
