For n-type semiconductor, which of the following statements is true?

The correct answer is Option (4) → Pentavalent atoms are the dopant and holes are the minority carriers.

In an n-type semiconductor:

• Pentavalent atoms (with 5 valence electrons) are added as dopants.

• Extra electrons become the majority charge carriers, while holes are minority carriers.

Answer: Pentavalent atoms are the dopant and holes are the minority carriers.
