Low-temperature galvanomagnetic transport coefficients of the two-dimensional hot electrons in GaAs quantum wells

Galvanomagnetic transport coefficients of the two-dimensional hot electrons in a square quantum well of GaAs were calculated for lattice temperatures of 4, 10 and 15 K using a heated Fermi-Dirac distribution function. Electron energy loss via screened deformation potential acoustic phonon scattering was considered. In electron momentum loss, background ionized impurity scattering was additionally incorporated. The magnetoresistance coefficient was found to be more sensitive than the Hall mobility to the changes in the channel width, magnetic field, and electric field.
