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 those of [16]. We also study the dependence of resistivity on temperature and parallel magnetic field. The Seebeck coefficient as a function of electron concentration and quantum well width are also calculated.
