Band gap - Simple English Wikipedia, the free encyclopedia

A band gap, also called a bandgap or energy gap, is an energy range in a solid where no electron states can exist. The term is used in solid-state physics and chemistry.Band gaps can be found in insulators and semiconductors.In graphs of the electronic band structure of solids, the band gap is the energy difference (in electron volts) between the top of the valence band and the bottom of the
