Abstract

A charge-trapping model is developed which does not require the assumption of shallow-level detrapping. The model shows the charge-trapping deficit to be proportional to S/sub 0/t/sup N/, where S/sub 0/ is the peak amplitude of the shaping amplifier pulse, t is the charge collection time for the carrier being trapped, and 1.5>
