Vedclass · Answer

(A) In semiconductors,the energy gap between the valence band and the conduction band is small. At low temperatures,electrons are unable to jump to the conduction band. As the temperature increases,more electrons gain sufficient thermal energy to jump from the valence band to the conduction band. This increase in the number of charge carriers leads to an increase in the conductivity of semiconductors.

The conductivity of semiconductors $..........$ with an increase in temperature.
