Where it comes from
From band + gap.
noun bandgaps · band gap
- The energy difference between two allowed ranges of electron energy in a solid; especially the difference between the energies of the valence band and the conduction band. The problem has been the lack of what is known as a bandgap. Semiconductors have bands of higher and lower energies and a point – the bandgap – at which excited electrons can hop from one to the other. This effectively allows switching on and off of the flow of current, so it is either conducting or
- A gap in a frequency range in which waves cannot propagate. The propagation of an acoustic wave inside a phononic crystal is forbidden in the bandgap frequency range due to Bragg scattering.
