For n-type semiconductor, which of the following statements is true? |
Trivalent atoms are the dopant and electrons are majority carriers. Trivalent atoms are the dopant and holes are majority carriers. Pentavalent atoms are the dopant and electrons are minority carriers. Pentavalent atoms are the dopant and holes are the minority carriers. |
Pentavalent atoms are the dopant and holes are the minority carriers. |
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. |
