Holes are minority carriers and pentavalent atoms are the dopants.

Vedclass · Answer

(C) In an $n-$type semiconductor,the majority charge carriers are electrons and the minority charge carriers are holes.To create an $n-$type semiconductor,silicon (a tetravalent element) is doped with pentavalent impurity atoms (such as phosphorus,arsenic,or antimony).These pentavalent atoms provide extra electrons to the conduction band,making electrons the majority carriers.Therefore,holes are the minority carriers and pentavalent atoms are the dopants.Thus,the correct statement is $(c)$.

In an $n-$type silicon,which of the following statements is true?
