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

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
