Band gap - Energy Eduion

A band gap is the distance between the valence band of electrons and the conduction band.Essentially, the band gap represents the minimum energy that is required to excite an electron up to a state in the conduction band where it can participate in conduction. The lower energy level is the valence band, and thus if a gap exists between this level and the higher energy conduction band, energy
