Abstract : The rate of momentum and energy relaxation of electrons in a polar semiconductor in a strong magnetic field is calculated. It is shown that the low field mobility in very strong magnetic fields is lower than in the fieldfree case but that the magnetoresistance at weaker applied fields also may be negative. To first order in the applied electric field the net energy of the electrons is shown to remain constant, but as a fraction of the average electron energy is in the form of translational energy the electron temperature drops below the lattice temperature as in the absence of a magnetic field.
