Physics - Semiconductors Question with Solution | TestHub

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

Each pentavalent atom donates one extra electron to the conduction band, significantly increasing the number of free electrons.

As a result, electrons become the majority charge carriers, making holes 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.
