Intrinsic & Extrinsic Semiconductors

When the conductivity of a semiconductor is only due to breaking of covalent bonds, the semiconductor is called

Show answer and solution

Answer: (b)

Conduction only from breaking of covalent bonds means no impurity carriers are present.
A pure (undoped) semiconductor is called intrinsic.
So the answer is (b) intrinsic.
