Abstract :
The amount of electron quasi-Fermi level splitting in the emitter-base junction of AlGaAs/GaAs single- and double-heterojunction bipolar transistors is computed. The degree of splitting is found to be generally small, and less pronounced in double-heterojunction devices. However, it is argued that the effect of the splitting on the current gain may be significant
