Question

In a P-type semiconductor, the acceptor impurity is:

• A. Just above the valence band
• B. Just below the conduction band
• C. Just above the conduction band
• D. Just below the valence band

Hint:

P-type semiconductors are doped with elements that create holes by accepting electrons, thus allowing current flow via hole conduction.

Answer 1

The Correct Option is D

Step 1: P-type semiconductor characteristics. In a P-type semiconductor, the acceptor impurities are atoms with one less electron than the semiconductor atoms, and they create holes just below the valence band.
Step 2: Conclusion. Thus, in a P-type semiconductor, the acceptor impurity is located just below the valence band.
