Abstract :
InAlAs/InGaAs/InP heterojunction bipolar transistor (HBT) structures were grown lattice-matched on InP substrates and metamorphically on GaAs substrates by molecular beam epitaxy. Generic structures with a thin base of 500 Å and doped at 4×1019 cm-3 were chosen to support the frequency response required for advanced wireless and fiber-optic telecommunication products. Beryllium- and carbon-doped large-area devices were found to exhibit similar DC characteristics. No significant difference in current gain or linearity was observed for metamorphic devices compared to their lattice-matched counterparts
