Physics - Semiconductors Question with Solution | TestHub

In an n-type semiconductor, pentavalent impurity atoms (such as phosphorus, arsenic, or antimony) are added to the intrinsic semiconductor.

Each pentavalent atom donates one extra electron to the conduction band. As a result, the number of electrons becomes much greater than the number of holes.

Thus, electrons are the majority charge carriers and holes are the minority charge carriers.

Therefore, the statement that holes are minority carriers and pentavalent atoms are dopants is true.

Answer: Holes are minority carriers and pentavalent atoms are dopants.
