An attempt is made to investigate theoretically the effects of varying the orientation of a quantizing magnetic field on the Einstein relation for the diffusivity-mobility ratio of the electrons in stressed Kane-type semiconductors, taking stressed n-InSb as an example. It is found, that the above ratio oscillates in a periodic manner with changes in the orientation of the magnetic field and increases with increasing electron concentration as expected in degenerate semiconductors. The ratio also exhibits oscillatory magnetic field dependence since the origin of the oscillations in the Einstein relation is the same as that of the Shubnikov de Hass oscillations. The corresponding well-known results for unstressed parabolic energy bands are also obtained from the generalized expressions as special cases.
