Vedclass · Answer

(C) Concept: $A$ $p$-type semiconductor is formed by doping an intrinsic semiconductor with trivalent impurities. These impurities create acceptor energy levels just above the valence band. At room temperature,these acceptor levels accept electrons from the valence band,creating a large number of holes in the valence band. Therefore,in a $p$-type semiconductor,the majority charge carriers are holes and the minority charge carriers are free electrons.
