  • Abstract
    The authors show clearly how dipole doping at the collector heterojunction in an InP/lnGaAs double heterojunction bipolar transistor improves device performance. Specifically, both fT and fmax are increased and the DC current-blocking is reduced. Also the DC switching characteristics, seen in devices with abrupt undoped InGaAs/InP collector heterojunctions, can almost be eliminated by using the dipole doping at that interface
