Significance of band gap
WebAnswer (1 of 13): Energy band gap is usually referred to the energy difference between the conduction band and the valence band. The conduction band is the outermost energy … In solid-state physics, a band gap, also called a bandgap or energy gap, is an energy range in a solid where no electronic states exist. In graphs of the electronic band structure of solids, the band gap refers to the energy difference (often expressed in electronvolts) between the top of the valence band and the … See more Every solid has its own characteristic energy-band structure.
