Webknown as the Burstein–Moss effect [4]. Band gap shrinkage due to heavy doping is a well known phe-nomenon in III-V compound semiconductors, particu-larly observed in GaAs by photoluminescence (PL) spectroscopy [3,5–11]. In the heterojunction-based devices, the band gap shift due to heavy doping result WebDec 20, 2012 · The results support the Burstein-Moss effect, where the optical band gap increases with the increase in the carrier concentration [18]. The electrical resistivity decreases rapidly in the substrate temperature range of 100–200 °C, approaches the minimum value of 1.3 × 10 −3 Ωcm for the film grown at 200 °C.
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… Web@article{osti_5038779, title = {Dynamic Burstein-Moss shift in semiconductor colloids}, author = {Kamat, P V and Dimitrijevic, N M and Nozik, A J}, abstractNote = …
