Abstract
Dissociation of free excitons into electrons and holes, due to collisi ons between the excitons and charge carriers accelerated by an in-plan e electric field in a multiple quantum well structure, is considered. We found that at normally used 2D excitonic concentrations the impact ionization process is rather strong and dominates over the exciton for mation process at electric fields of the order of a few hundred V cm(- 1).
