Group Wiki Page:
The Band Gap Energy
The band gap energy is the energy needed to break a bond in the crystal. When a bond is broken, the electron has absorbed enough energy to leave the valence band and “jump” to the conduction band. The width of the band gap determines the type of material (conductor, …
