Burstein moss shifting
WebOct 1, 1998 · The Burstein-Moss (BM) shift was accounted for using a Fermi level filling factor in addition to the excitonic and BBCE terms. While for the p-type samples the BM shift exhibited only parabolic effects, the n-type samples had pronounced non-parabolicity at the highest doping level, in agreement with a bandstructure calculation. WebBurstein–Moss shift, an increase in the absorption edge (optical band gap) with increasing doping level, is explored. The optical gap increases on the order of 0.1eV for doping levels ranging from 3×1018 to 2×1020 cm−3, relevant doping levels for good thermoelectric materials. Chemical potential is
