Choose the only false statement from the following.

Options

A. In conductors the value of conduction bands may overlap.
B. Substance with energy gap of the order of 10 eV are insulators.
C. The resistivity of a semiconductor increases with increase in temperature.
D. The conductivity of a semiconductor increases with increase in temperature.

Answer

C

Explanation

The resistivity of a semiconductor increases with increase in temperature.
The resistivity (reciprocal of conductivity) decreases with increasing temperature.
