Abstract

A new functional AlGaAs/InGaAs/GaAs heterostructure-emitter and heterostructure-base transistor (HEHBT) with pseudomorphic base structure is presented. Due to the insertion of InGaAs quantum well between emitter-base (E-B) junction, the valence band discontinuity can be enhanced and a high emitter injection efficiency may be achieved. In addition, an interesting S-shaped multiple negative differential resistance (MNDR) phenomenon is observed under the inverted operation mode. This may be attributed to an avalanche multiplication and sequential two-stage barrier lowering effect resulting from electrons accumulation at AlGaAs/GaAs heterointerface and InGaAs quantum well, respectively.
