Question

State whether given statement is True or False
The resistance of intrinsic semiconductors increase with increase in temperature

• A. True
• B. False

Answer 1

The correct option is B False

In a semiconductor, conductivity is due to the movement of electron - hole pairs, As the temperature is increased covalent bonds breaks and more electron - hole pairs are available for conduction. Thus conductivity increases and resistivity is the reciprocal of conductivity, so it decreases.

Therefore the resistance decreases with increase in temperature.
