SPACE-CHARGE RECOMBINATION IN P-N-JUNCTIONS WITH A DISCRETE AND CONTINUOUS TRAP DISTRIBUTION

Space charge Shockley-Read-Hall recombination currents in the presence of discrete or continuous distributions of recombination centres are analysed. For a single level trap, depending on its position inside th e forbidden band, asymptotic values both for the ideality Factor of th e current-voltage characteristic and for the activation energy of the saturation current are obtained. The analysis is extended to continuou s trap distributions and the current-voltage characteristics obtained are explained in terms of the simple theory developed for single level traps.
