Question

what is the importance of energy gap in a semiconductor​

Answer 1

Answer:

Energy band gap differentiates the metals into conductor, insulator, semiconductor. Energy band gap is usually referred to the energy difference between the conduction band and the valence band. The conduction band is the outermost energy band where the free electrons lie and below that there is the valence band.
