Question
When a hole is produced in P-type semiconductor, there is:
✓
Answer
- Missing electron in valence band
A hole is not itself a physical quantity but a missing electron in valence band. An electron from adjacent site jumps to fill this hole and thus creates a hole at its former site. So it seems as if the hole itself has moved.
