Abstract
AlGaAs/GaAs npn heterojunction bipolar transistors grown by molecular beam epitaxy on Si (311) substrates and fabricated using a self-aligned base contact process are reported. Reflection high energy electron diffraction patterns correlate with antiphase domain-free growth. Preliminary DC measurements for 70×70 μm2 device reveal a small-signal common-emitter current gain of 10 and a collector-emitter breakdown voltage of 13 V
