- both the valence band and conduction band are completely occupied
- the valence band is completely occupied and the conduction band is completely empty
- both the valence band and conduction band are completely empty
- the valence band is completely occupied and the conduction band is partially occupied
- the valence band is completely empty and the conduction band is completely occupied
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
• At absolute zero:
• No thermal excitation
• All electrons stay in valence band
Step 1: Band structure
Valence band → fully filled
Conduction band → completely empty Final Conclusion:
