Question

The gap between the top of valence band and bottom of conduction band at o K is
called
​

Answer 1

Answer:

The gap between the top of the valance band and the bottom of the conduction band is called energy band gap

Answer 2

The gap between the top of the valence band and the bottom of the conduction band at 0 K is called the Energy Band Gap.

• The energy band-gap between the valence band and conduction band is the energy difference between the two bands which is measured in eV.
• The conduction of electrons from the valence band to the conduction band causes the flow of current in materials.
• The energy band-gap for conductors is small and electrons are easily transferred to conduction-band hence they conduct electricity easily.
• Whereas, in semiconductors, the energy-band gap is more than the conductors but less than insulators.
• And in insulators, the energy-band gap is maximum, and electrons are not transferred to the conduction band and thus insulators are not capable of conducting electricity.
