Abstract

The advantages of using Sb containing III-V compounds in bipolar type devices are discussed with recent experimental results of two different applications of GaAsSb in Heterojunction Bipolar Transistors (HBTs). The performance of a prototype AlGaAs/GaAsSb/GaAs double HBT (DHBT) that exhibits a current gain of five and a maximum collector current density of 5 X 10⁴ A/cm² and a pnp AlGaAs/GaAs HBT with a superlattice GaAsSb emitter ohmic contact, with specific contact resistivity of 5 +/- 1 X 10^-7 (Omega) -cm² across the sample, are examined.
