Question

For semi conductorss , metals and insulators what are the band gap

Answer 1

● Valency band or band gap plays a major role in the conductivity of metals.

● Insulators are the metals which can not conduct electricity and they have large gap between the valency bands and conduction band.

● semiconductors are not good conductors but can conduct electricity to some extent as there is moderate gap between valence band and conduction band in a metal.

● Conductors are the metals which can conduct electricity to a great extent as the valency band and conduction band has no gap between them.
