Updated On: Apr 26, 2026
- the conduction band.
- the valence band.
- the band gap and are close to the conduction band.
- the band gap and are close to the valence band.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
In n-type semiconductors, pentavalent impurities create "Donor Energy Levels".
Step 2: Analysis
These donor levels are located within the forbidden energy gap, just below the bottom of the conduction band.
Step 3: Logic
Because they are very close to the conduction band, electrons can easily be thermally excited into the conduction band.
Step 4: Conclusion
The levels are in the band gap, close to the conduction band.
Final Answer: (C)
