  • Abstract
    InP/In0.53Ga0.47As/InP double heterojunction bipolar transistors (HBTs) were grown on GaAs substrates. InP layer was employed as a metamorphic buffer layer because of its high thermal conductivity. A 140 GHz power-gain cutoff frequency fmax and a 207 GHz current-gain cutoff frequency fτ were obtained, presently the highest reported values for metamorphic HBTs. The breakdown voltage BVCEO was 6 V while the DC current gain β was 76.
