In an semiconductor the separation between conduction band and valence band is of the order of

Statement I : Electrical conductivity of semiconductors increases with rise in temperature. Statement II : There is a small energy gap between conduction band and valence band.

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

In a good conductor the energy gap between the conduction band and the valence band is

Assertion (A): As the temperature of a semiconductor increases, its resistance decreases. Reason (R ): The energy gap between conduction band and valence band is small.

Assertion: LED is used in display units because it emits light when current passes through it. Reason: In LED, electrons comes from conduction band to valence band when it emits energy.

Statement-1 : When the temperature of a semiconductor is increased, then its resistance decreases. Statement-2 : The energy gap between conduction band and valence band is very small for semiconductor.

Assertion: If there is some gap between the conduction band and the valence band, electrons in the valence band all remain bound and no free electrons are available in the conduction band. Then the material is an insulator. Reason: Resistance of insulators is very low

In a good conductor, what is the energy gap between the conduction band and the valence band.?
