The energy band lying above the valence band is called the:
AConstrained band
BConduction band
CConductive band
DConstructed band
Answer & Solution
Correct answer: B. Conduction band
1. Two bands matter for conduction in a solid.
2. The upper one is where electrons are free to move.
3. The energy band above the valence band is called the conduction band.
4. So the answer is the conduction band.
