Abstract
InGaAs/InP double-heterostructure bipolar transistors (DHBT\´s) with current gain β ∼ 630 have been realized using gas-source molecular beam epitaxy (GSMBE). These devices exhibit near-ideal β versus IC characteristic (i.e., β independent of IC ) with a small-signal gain

for a high-quality AlGaAs/GaAs HBT grown by OMCVD. The higher emitter injection efficiency at low collector current levels found in the InGaAs/InP DHBT is due to at least a factor 100 smaller surface recombination current.
