Carbon-doped base InGaP/GaAs single and double heterojunction bipolar transistors (HBTs) grown by gas-source Metal Organic Molecular Beam Epitaxy (MOMBE) are reported. Large are devices (emitter diameter 70 μm) exhibited gain of 25 for high injection levels at a base doping of 5 × 1019 cm−3. Ideality factors (<1.1)were obtained for both emitter-base and base-collector junctions in both single (SHBT) and double PHBT) heterojunction devices. Vceo's of 12 V and 19 V for SHBTs and DHBTs respectively were measured.

Current Blocking

The dc and rf characteristics for InP/InGaAs heterojunction bipolar transistors having a single heterojunction design were measured and compared with those for double heterojunction devices that employ a composite collector. Although the composite-collector design improves the breakdown characteristics of our devices the rf performance was not as good. This we partially attribute to the collector heterojunction, which causes "current blocking".
