Abstract :
We investigated the electrical characteristics of InGaP/GaAs heterostructures. We found that Sb doping significantly improves the carrier profile at the heterointerface. InGaPSb-channel FETs, InGaPSb channel DH-HEMTs, and InGaPSb HBTs are also studied. We obtained good performance of these structures, suggesting InGaPSb can be used to device structures
