Moss–Burstein effect - Wikipedia

The Moss-Burstein effect, also known as the Burstein–Moss shift, is the phenomenon in which the apparent band gap of a semiconductor is increased as the absorption edge is pushed to higher energies as a result of some states close to the conduction band being populated. This is observed for a degenerate electron distribution such as that found in some degenerate semiconductors an… WebMoss-Burstein effect 莫斯-布尔斯坦效应.
