Question

On increasing the temperature of semiconductor, its resistance : (A) decreases (B) increases (C) depends on pressure (D) does not depend on temperature

Tardigrade Admin · Accepted Answer

At room temperature, valence band and conduction band in a semiconductor are half filled.
Due to increase m temperature, the more electrons present in valence band acquire sufficient amount of energy and jump to conduction band. In this way, the resistance of semiconductor decreases.

Q. On increasing the temperature of semiconductor, its resistance :

decreases

increases

depends on pressure

does not depend on temperature
