  • Abstract
    The emitter efficiency current gain βγis calculated taking into account the effect of the bandgap decrease caused by heavy doping of the emitter. It is found that this effect reduces the emitter efficiency and explains experimental results on the temperature dependence of the current gain. It also predicts an optimum emitter doping for a given base doping.
