Q. State whether given statement is True or False
The probability of electrons to be found in the conduction band of an intrinsic semiconductor at a finite temperature decreases exponentially with increasing bandgap.

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

Q. Assertion :If the temperature of a semiconductor is increased then its resistance decreases. Reason: The energy gap between conduction band and valence band is very small.
