Vedclass · Answer

(A) In a transistor,the base region is designed to be very thin and lightly doped. This configuration minimizes the recombination of charge carriers (holes or electrons) within the base region. As a result,the majority of charge carriers injected from the emitter can pass through the base and reach the collector. Specifically,this design enables the collector to collect approximately $95\%$ of the charge carriers coming from the emitter side.

In a transistor,the base is made very thin and is lightly doped with an impurity because:
