Abstract :
GaAs/GaInP heterojunction bipolar transistors grown by chemical beam epitaxy with highly Be-doped base layers have been found to be stable under electrical stress. The devices did not exhibit any DC current gain change when operated at a collector current density of 4*104 A/cm2 and an emitter collector voltage of 3 V for 100 h.
