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 … 더 보기 Every solid has its own characteristic energy-band structure. This variation in band structure is responsible for the wide range of electrical characteristics observed in various materials. Depending on the dimension, the band … 더 보기 In materials with a large exciton binding energy, it is possible for a photon to have just barely enough energy to create an exciton (bound … 더 보기 • Aluminium gallium arsenide • Boron nitride • Indium gallium arsenide • Indium arsenide 더 보기 • Direct Band Gap Energy Calculator • Moriarty, Philip. "Energy Gap (and what makes glass transparent?)". Sixty Symbols. Brady Haran for the University of Nottingham. 더 보기 In photonics, band gaps or stop bands are ranges of photon frequencies where, if tunneling effects are neglected, no photons can be transmitted through a material. A material exhibiting this behaviour is known as a photonic crystal.
