WebBase-emitter junction is forward biased and collector-base junction is reverse biased Electrons “emitted” into base much more than holes since the doping of emitter is much higher Magic: Most electrons cross the base junction and are swept into collector Why? Base width much smaller than diffusion length. Base-collector WebThe forward biased from base to emitter narrows the BE depletion region while the reverse bias from the base to collector widens the BC depletion region. However, due to the flow of currrent in the base and the abundance of current carriers int the collector (heavily doped), the excess carriers from the emitter to the collector (through the base).
