Abstract:
1. A bipolar semiconductor component operable to enter an on-state or an off-state, the component comprising: a base region that is adapted in the on-state to accommodate a charge carrier plasma with p-type and n-type charge carriers; a recombination rate control structure, the control structure comprising a dielectric layer adjoining the base region, a control electrode separated from the base region by the dielectric layer, and recombination centers; and a drive circuit for the recombination rate control structure that is adapted to apply a control voltage between the control electrode and the base region, based on a transition between the on-state and the off-state in the component, the control voltage being selected such that an electric field is generated in the base region that reduces the concentration of charge carriers of one of the p-type and n-type type in the region of the recombination centers.
