Question

When the electrical conductivity of a semiconductor is due to the breaking of its covalent bonds, then the semiconductor is said to be

• A. Donor
• B. Acceptor
• C. Intrinsic
• D. Extrinsic

Answer 1

The correct option is C Intrinsic

The electrical conductivity of a semiconductor is due to the breaking of its covalent bonds, this means that the semiconductor does not have any charge carriers of its own, in the beginning.

This is true for intrinsic semiconductors as the atoms in it have their octet completed and therefore, lack any free electrons.

Hence, $\left(C\right)$ is the correct answer.
