Burstein–moss effect
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 WebMoss-Burstein effect 莫斯-布尔斯坦效应. Provided that the effective masses of the valence and conduction bands are known reasonably accurately and it is assumed that the curvature and position of the bands are independent of the doping, the shift in energy can be used as an accurate and contactless method of determining the carrier ...
