Thermally stimulated current transport peaks in insulating layers with spatially non-homogeneous trap distribution. II. Bulk initial carrier generation

Abstract

In the present paper the authors continue the recent investigations of Tomaszewicz et al on the influence of spatial non-homogeneity of the trap distribution on thermally stimulated currents (TSC) due to transport of carriers in insulating layers. They consider here-in contrast to the previous work-the case of bulk initial generation of carriers. For both non-dispersive and dispersive transport, the analytical formulae obtained agree satisfactorily with the results of Monte Carlo simulation. The possibility of determining the spatial trap distribution on the basis of the measured TSC is discussed.
