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… WebDec 27, 2024 · The change in the E opt of heavily doped semiconductors is usually explained by the Burstein-Moss shift (BMS) and bandgap renormalization (BGR), which cause the Fermi level to change in opposite ...

WebApr 9, 2024 · This can be explained by the Burstein–Moss effect (blue shift), which refers to the expansion of the energy band gap by changing the electronic band structure of a film [57,58]. 4. Conclusions. Cu 2 O films were prepared on glass substrates via RF magnetron sputtering at various substrate temperatures (25 °C to 400 °C). WebIn n-type GaAs, the Burstein-Moss shift predominates because of the lower effective mass for electrons. causing a significant shift of the Fermi level into the conduction band For similar doping densities in p-type GaAs, however, the heavier hole mass permits only a negligible Burstein-Moss shift.
