Abstract
The equations for multiple-trapping transport under conditions of pulse injection have been solved for a macroscopically nonhomogeneous spatial trap distribution (STD). Since the influence of the STD on transient currents is the main point of interest, the authors deal only with two model energetic trap distributions-monoenergetic for non-dispersive transport and exponential for dispersive transport. The expressions for transient currents obtained are discussed with respect of their utility in determining STD on the basis of experimental transients. Analytically calculated transient currents agree perfectly with the results obtained from the Monte Carlo simulation of these transients.
