The band just above the valence band is the:
ADepletion layer
BConduction band
CForbidden region
DImpurity levels
Answer & Solution
Correct answer: B. Conduction band
1. Free electrons need a band they can move in.
2. It lies immediately above the filled band.
3. That is the conduction band.
4. So the answer is conduction band.
