bandgap

   Also found in: Encyclopedia, Wikipedia 0.06 sec.
bandgap  (bndgp)
The difference in energy in a substance between electron orbitals in which the electrons are not free to move (the valence band) and orbitals in which they are relatively free and will carry a current (the conduction band). In semiconductors, some electrons are sustained in the conduction band by thermal energy. Energy released when an electron in the conduction band falls into a hole in the valence band is called bandgap radiation. See also holesemiconductor laser
