Abstract :
We present the growth of highly carbon doped GaAsSb on InP substrate with LP-MOVPE and nitrogen carrier gas. Carbon doped GaAsSb lattice matched on InP is of pronounced interest for high speed double heterostructure bipolar transistors. We observed a significant effect of the nitrogen carrier gas on the growth behavior which results in a lower distribution coefficient. A linear doping behaviour with small CBr4 flows up to p=4×1019 cm-3 can be observed and first realized DHBT structures show preliminary fT and fMAX values of 100 GHz and 60GHz, respectively.
