In this work, the temperature-dependent DC performance of InP/GaAsSb double heterojunction bipolar transistors (DHBTs) with an InP/InAlAs composite emitter was characterized. The current transport mechanisms in DHBTs with a type-I InAlAs/GaAsSb emitter–base junction interface and a type-II GaAsSb/In...
