Abstract :
InGaAs/InP single heterojunction bipolar transistor (SHBT) is the fastest HBT owing to its high current density and high electron saturation velocity. This work proposes a new structure with a GaAsSb/InGaAs B-C junction to improve upon the conventional SHBT. GaAsSb base material is used to maximize the conduction and valence band discontinuity in the lattice match material system.
