Abstract :
The fabrication of the first GaAs-GaAsSb based heterojunction bipolar transistor is reported. Maximum current gains of 25 at a base current of 1 mA have been measured on devices employing a p-type 1000 AA GaAs0.93Sb0.07 base doped at 1*1019 cm-3 and GaAs emitter and collector regions with graded heterointerfaces. At present, devices so fabricated show unstable behaviour.
