Abstract :
A new model for the HBT has been developed which solves for the electrical and photogenerated currents in base, emitter and collector. The model accounts for the discontinuity in quasi-fermi level by defining an effective carrier interface velocity. Experimental and theoretical curves relating to the device behavior are presented and compared.<>
