Practice question from Semiconductor Electronics (Class 12 · CBSE · Science Physics), with the correct answer and a step-by-step solution.
medium · MCQ · Q-4E38FE
In a p-type semiconductor, the Fermi level lies:
- A.Exactly in the middle of the forbidden energy gap
- B.Close to the conduction band edge
- C.Close to the valence band edgeCorrect answer
- D.Outside the forbidden energy gap
Solution
In a p-type semiconductor, holes are the majority charge carriers and acceptor energy levels are created just above the valence band. As a result, the Fermi level shifts downwards towards the valence band edge.
