The conductivity of a semiconductor depends upon

Assertion : Electrical conductivity of intrinsic semiconductors increases with increasing temperature. Reason : With increase in temperature, large number of electrons from the valence band can jump to the conduction band.

Statement 1: Electrical conductivity of intrinsic semiconductors increases with increasing temperature. Statement 2: With increase in temperature, large number of electrons from the valence band can jump to the conduction band.

The electrical conductivity of an intrinsic semiconductor at 0 K is
