Question

In the energy band of an N-type semiconductor doped with Phosphorus, the donor level of Phosphorus is
Options
A closer to the valence band than the conduction band
B halfway between the conduction and valence bands
C overlapping with the valence band
D closer to the conduction band than the valence band
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

In N-type material, the pentavalent dopant (phosphorus) creates a shallow donor energy level lying just below the conduction band, making it easy for its extra electron to be thermally excited into the conduction band.

Hint

Donor levels in N-type semiconductors sit just below which band — the one the extra electron needs to reach?
