Abstract :
Recent analytical investigations of nonlinear photoconductive switches are discussed. The dependencies of semiconductive parameters on the electric field in conjunction with the nonuniform space charge distribution (due to contact injection) appear to be of some importance in nonlinear photoconductive switching. The authors discuss a computer model under development that addresses the spatial dependencies of nonlinear photoconductive switching. This model takes into account the recombination dependence of diffusion associated with double injection. In addition, the model includes field-dependent trapping parameters and mobilities. The relevant equations are presented along with the preliminary results of the computer model
