  • Abstract
    AlGaAs/GaAs pnp narrow-base heterojunction bipolar transistors (HBTs) exhibiting low collector cut-in voltages (0.25-0.3 V) and operation at collector current densities of >1.5*104 A/cm2 have been fabricated. Devices with a base width of 50 AA and nominal base doping densities of 3, 6, and 9*1018 cm-3 exhibit maximum common-emitter DC current gains of 105, 21 and 5, respectively.
