A Quantum-Switched Heterojunction Bistable Bipolar Transistor
01 January 1989
The purpose of this work is to demonstrate a novel bistable transistor -- the quantum-switched heterojunction bistable bipolar transistor (Q-switched HB sup 2 T). With increasing base-emitter voltage, as shown in Fig. 1, the collector current is switched from high to low, while the base current is switched from low to high. The Q-switched HB sup 2 T has potential applications in implementing high-speed single-bipolar-transistor memory cells, gain-quenching in light-emitting devices, and opto-electronic switching.
