- 1When a trivalent impurity is added to a semiconductor, it introduces an acceptor energy level near the valence band.
- 2The addition of trivalent acceptor impurities to a semiconductor results in the creation of holes in the valence band.
- 3The addition of trivalent acceptor impurities to a semiconductor results in the creation of mobile holes directly in the conduction band.✓
- 4When a pentavalent impurity is added to a semiconductor, it introduces a donor energy level near the conduction band.
Correct answer
The addition of trivalent acceptor impurities to a semiconductor results in the creation of mobile holes directly in the conduction band.
