Substances such as gallium arsenide with a direct one of these can emit light and are thus frequently used in LED's. Metals have a negative value for this quantity that decreases as temperature is raised, explaining why the conductivity of semiconductors increases with increasing temperature. FTP identify this quantity that is defined as the energy difference between the top of the valence band and the bottom of the conduction band, often abbreviated E-sub-G.
