Comparison of main models for generation-recombination space-charge current in abrupt p-n junction

The principal approaches of modelling the generation-recombination current in the space-charge region are compared in the case of an abrupt p-n junction submitted to small bias voltages. It is shown that it is possible to model this parameter without any need to know the x-variation of the potential in the space-charge region. The results obtained by our model are in good agreement with those of the “exact model”
