Question

Effect of temperature for semi conductor on resistance

Answer 1

Description

With increase in temperature, the conductivity of the semi-conductor material increases. As with increase in temperature, outermost electrons acquire energy and hence by acquiring energy, the outermost electrons leave the shell of the atom.

Hence with increase in temperature, number of carriers in the semiconductor material increases and which leads to increase in conductivity of the material. So we call the semi-conductor material have negative temperature coefficient i.e. with increase in temperature, resistance decreases.
