- 1The position of the Fermi level in a p-type extrinsic semiconductor moves towards the conduction band with an increase in the doping concentration of trivalent impurities.
- 2The position of the Fermi level in an n-type extrinsic semiconductor moves towards the conduction band with an increase in the doping concentration of pentavalent impurities.✓
- 3The position of the Fermi level in a p-type extrinsic semiconductor moves towards the valence band with an increase in the doping concentration of pentavalent impurities.
- 4The position of the Fermi level in an n-type extrinsic semiconductor moves towards the valence band with an increase in the doping concentration of pentavalent impurities.
Correct answer
The position of the Fermi level in an n-type extrinsic semiconductor moves towards the conduction band with an increase in the doping concentration of pentavalent impurities.
