摘要
Common-emitter current gains of 115 and 170 are achieved in transistors with emitter dimensions as small as 0.3 × 3 and 0.8 × 3 μm2, respectively. These results are comparable with scaling experiments reported for Si bipolar devices and represent a significant improvement over AlGaAs/GaAs heterostructure bipolar transistors. Both the low surface recombination velocity and nonequilibrium carrier transport in the thin (800-angstrom) InGaAs base enhance the DC performance of these transistors.
