    Abstract

    We use a bipolar Ensemble Monte Carlo embedded within a circuit solver to include the nonlinear transport of photogenerated electron-hole plasmas. All the usual carrier-carrier and carrier-phonon scattering mechanisms are included within a static screening model to incorporate non-ohmic behaviour. A one dimensional Poisson solver combines nonuniform field effects brought about by charge redistribution. Unlike previous EMC simulations for photoconductive circuits, we allow for transient changes in the net mobile charge within the photoexcitation region, by appropriately modifying the supercharge associated with each particle. Using this time varying supercharge scheme, we test an N+-N-N+ structure under both dc and transient conditions.
