摘要：
We report the fabrication and characterization of abrupt junction InP/GaAsSb/InP DHBTs with a current gain cutoff frequency f(T) and a maximum oscillation frequency f(MAX) above 200 GHz with a breakdown voltage BVCEO > 6 V. This level of performance was reached by thinning the base layer to 200 Angstrom and increasing the C- doping level to similar to 10(20) /cm(3) while using a 2000 Angstrom thick InP collector layer.
