Question

What happens to the resistivity of semiconductors with the increase of temperature?

Answer 1

1. In semiconductors, at room temperature or above the room temperature, some electrons may move freely.
2. In semiconductors, if the temperature is increased, then the concentration of charge carriers will also increase. As a result, the conductivity of semiconductors will be increased.
3. So, when conductivity will be increased, the resistivity of a semiconductor will be decreased.

Hence, the resistivity of semiconductors will decrease with the increase in temperature.
