M.I.S. capacitance in heavy inversion

The letter deals with a theoretical analysis of the different currents originating in an m.i.s. structure for a heavy inversion region of operation, when a transient low-level electrical perturbation is applied. The expression for the generation-recombination current in the space-charge region is fairly different from that generally used; it is emphasised that the recombination rate is not constant and not equal to ni/2¿n in the whole thickness of the transition zone.
