bandgap
bandgap noun: 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.
Noun
bandgap (plural bandgaps)
- 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...2024 January 4, Matthew Sparkes, “First working graphene semiconductor could lead to faster computers”, in New Scientist, retrieved 18 Jan 2024
- 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.
