摘要：

The first N-Al0.22Ga0.78As emitter, p-Ge base, and n-GaAs collector (AIGaAs/Ge/GaAs) heterojunction bipolar transistor (HBT) has been grown by molecular beam epitaxy. Devices exhibited common-emitter current gains of as high as 300 at a collector current density of 2000 A/cm2 and a collector voltage of 4 V. As the device area is reduced from 50 × 50 to 10 × 40 µm, the current gain did not show significant changes, suggesting a low surface recombination velocity in the Ge base. © 1990 IEEE
