In an extrinsic semi-conductor charge carriers are
Correct answer: D. Both a and b
- A. Holes
- B. electron
- C. No charge carriers
- D. Both a and b
Explanation
Extrinsic semiconductors are those whose conductivity is due to impurities. Extrinsic semiconductors are of two types: n-type and p-type. In n-type semiconductors, the majority charge carriers are electrons, and in p-type semiconductors, the majority charge carriers are holes
