Vedclass · Answer

(C) In a transistor,the base is made very thin and lightly doped to ensure that the majority of charge carriers injected from the emitter into the base pass through to the collector.If the base were heavily doped,the number of majority charge carriers in the base would be high.This would lead to a higher rate of recombination between the injected charge carriers from the emitter and the majority charge carriers in the base.By keeping the base lightly doped,the recombination rate is significantly decreased,which allows most of the charge carriers to reach the collector,thereby increasing the current gain of the transistor.

In a transistor,the base is very lightly doped as compared to the emitter because by doing so:
