Abstract
The low-field magnetotransport properties of a two-dimensional electron gas are calculated for a situation in which more than one subband is occupied. The theory is formulated in terms of a Boltzmann transport equation in which only elastic impurity scattering is taken into account. The possibility of intersubband scattering is included and its effect on the transverse magnetoresistance and Hall coefficient is determined. We find that intersubband scattering plays an important role and its neglect can lead to erroneous conclusions regarding the values of the subband mobilities extracted from fits to experimental data.
