Vedclass · Answer

(C) In an $n$-type semiconductor,the semiconductor is doped with pentavalent impurity atoms (like $P$,$As$,$Sb$).These pentavalent atoms provide extra electrons to the conduction band,making electrons the majority charge carriers.Conversely,holes are generated only due to thermal excitation,making them the minority charge carriers.Therefore,electrons are majority carriers and pentavalent atoms are dopants,while holes are minority carriers.Comparing this with the given options,option $C$ is correct because it states that holes are minority carriers and pentavalent atoms are dopants.
