Abstract:We consider the mobility of a quasi-twodimensional electron gas in a GaP/AlP/GaP quantum well with a valley degeneracy g 1 for quantum well width L < Lc = 45.7 Å and a valley degeneracy of g 2 for quantum well width L > Lc = 45.7 Å. We calculate the mobility as a function of electron density for interface-roughness and impurity scattering with using different approximations for the local-field correction. In the case of zero temperature and Hubbard local-field correction our results reduce to tho… Show more
