Q. Assertion The resistivity of a semiconductor increases in temperature.
Reason In a conducting solid, the rate of collisions between free electrons and ions increases with increase of temperature.

Semiconductor Electronics: Materials Devices and Simple Circuits

Solution:

Resistivity of semiconductor decreases with temperature. The atoms of a semiconductor vibrate with large amplitudes at higher temperatures there by increasing conductivity not resistivity.
