Websimulator currently used relies on experimental data to be calibrated and the RSH Recombination model only characterizes molecules as far as carbon number. The methodology used consist in replicating the experimental conditions in the simulator, and then comparing the results with the ones obtained experimentally. WebThe physical processes of charge generation and recombination were investigated by SAH, et al. (2) who give a recombination rate of about ni Ur~o-gea - (1) 2ro for a reverse biased unsymmetrical p-n junction depletion region with the generation-recombina- tion centres located close to the Fermi level on the energy diagram.
