Abstract
All the previous homogeneous theories result in M(xx) = 0 which are at variance with the experimental data. It is for this reason, previous theories have consistently used experimental value of M(xx) in calculating thermopower tenser ($) over right arrow S. The inhomogeneous and non-equilibrium formalism proposed by Dyakin et al. was generalized to including both transverse and longitudinal modes of electron-phonon interaction and considering the broadening of the Landau level. The resulting formula gives theoretical values of M(xx) for GaAs/AlGaAs heterojunctions which are in accord with experimental,data at oscillation phases but (lambda(p)/[z])(1/2) times smaller than experimental data for T = 1.275 K, 2.937 K, 5.005 K and C = 0.20 where lambda(p) and [z] are the phonon mean free path and effective thickness of the heterojunctions, By means of the semi-empirical formula of M(xx) with extra factor (lambda(p)/[z])(1/2) in, phonon drag magnetothermopower can be calculated from theoretical values of M(yx) and M(xx).
