Abstract:
1. A semiconductor light-emitting transistor device, comprising: a bipolar pnp transistor structure having a p-type collector, an n-type base, and a p-type emitter; a first tunnel junction coupled with said collector, and a second tunnel junction coupled with said emitter; and a collector contact coupled with said first tunnel junction, an emitter contact coupled with said second tunnel junction, and a base contact coupled with said base; said first tunnel junction comprising a layered n+/p+ region with the n+ layer of said n+/p+ region being coupled with said collector contact and the p+ layer of said n+/p+ region being coupled with said collector; whereby, signals applied with respect to said collector, base, and emitter contacts causes light emission from said base by radiative recombination in said base.
