  • Abstract
    AlGaAs/GaAs HBTs with compositionally-graded carbon-doped base layers were grown by conventional low-pressure MOCVD for the first time. A high current gain of 100 obtained for a very high base doping of 8*1019 cm-3 indicates the high crystal quality of the AlGaAs graded base layer.
