MCQ
A pure semiconductor at absolute zero has :
- AAbsence of electrons in the conduction band.
- BAll the electrons occupying the valence band.
- CLarge $E_g$ value.
- ✓All of the above.
✓
Answer
Correct option: D.
All of the above.
At absolute zero temperature, in a pure semiconductor, all electrons occupy the valence band and no electrons are present in the conduction band. The forbidden gap energy $E_g$ is large.
