Vedclass · Answer

(C) When a pentavalent impurity (donor impurity) is added to an intrinsic semiconductor (like $Si$ or $Ge$),each donor atom provides an extra electron to the conduction band.Since the number of free electrons increases significantly,the semiconductor becomes an $n$-type semiconductor.In an $n$-type semiconductor,electrons are the majority charge carriers and holes are the minority charge carriers.
