Question

Electrical conductivity of semiconductors increases with increase in ____________.

पर्याय

• pressure

• density

• mass

• temperature

Answer 1

Electrical conductivity of semiconductors increases with increase in temperature.

Explanation:

The gap between the valence band and the conduction band in semiconductors is tiny. As a result, some electrons may move into the conduction band and exhibit conductivity. Because more electrons can leap to the conduction band as temperature rises, semiconductors' electrical conductivity rises. Intrinsic semiconductors are materials that exhibit this type of behaviour, such as silicon and germanium.
