Question:
The donor level in an n-type semiconductor lies ________.
The donor level in an n-type semiconductor lies ________.
Show Hint
Donor level (n-type): Near CB; Acceptor level (p-type): Near VB.
Updated On: Jun 26, 2026
- just below the conduction band
- exactly at the middle of the band gap
- just below the valence band
- just above the conduction band
- on the valence band
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
In n-type semiconductors, pentavalent impurities provide extra electrons.
Step 2: Meaning
These extra electrons require very little energy to become free charge carriers.
Step 3: Analysis
The energy level of these donor electrons must be very close to the Conduction Band (CB) to allow easy excitation.
Step 4: Conclusion
The donor energy level is located just below the conduction band. Final Answer: (A)
