MHT CET · Physics · Semiconductors
At room temperature, a p-type semiconductor has
- A equal number of free electrons and holes.
- B large number of free electrons and few holes.
- C large number of holes and few electrons.
- D no electrons or holes.
Answer & Solution
Correct Answer
(C) large number of holes and few electrons.
Step-by-step Solution
Detailed explanation
Concept: P-type semiconductor is doped with trivalent impurities which generate acceptor levels near the valence band. Therefore, the majority carriers are holes and the minority carriers are electron.
