Crystal bandgap
WebPhotonic Bandgap Photonic crystals are a powerful tool for the manipulation of optical dispersion and density of states. By utilizing the tools of lattice simulation, we can engineer photonic systems that have a variety of interesting band structures. WebJul 23, 2010 · Sets of states that are not possible form regions between those bands, and these are called bandgaps. The bands closest to the atomic nucleus, called core levels, and the furthest band from the nucleus that has electrons in it, called the valence band, all keep their electrons tightly in place.
