V. Ryzhii, THE BISTABILITY EFFECT IN RESONANT-TUNNELING PHOTOTRANSISTORS WITH MULTIPLE-QUANTUM-WELL STRUCTURE, Semiconductor science and technology, 9(6), 1994, pp. 1209-1214
Bistable operation of resonant-tunnelling phototransistors incorporati
ng a multiple quantum well base (RTQWPT) is reported. The mechanism of
operation is resonant-tunnelling hot-electron injection controlled by
electron photoemission from the multiple quantum well base into the c
ollector. The RTQWPT utilizes intersubband optical absorption in the i
nfrared region of the spectrum. The RTQWPT can be used as a high-effic
iency optoelectronic switch controlled by infrared radiation and an in
frared photodetector.
