“…In spite of the large efforts made in recent years to understand the physics of narrow-gap semiconductors, the quantitative description of the basic magneto-transport in narrow-gap semiconductors is still incomplete. Most of previous theories about magneto-transport' [1][2][3] ' are based on the assumption that the energy bands in semiconductors are parabolic. These theories are no longer appropriate for narrow-gap semiconductors.…”

The balance equations are used to investigate the hot electron magneto-transport in narrow-gap semiconductor InSb at 77 K in crossed weak magnetic field and electric field. In the case of vanishing transverse velocity, the drift mobility and the Hall mobility are calculated and it is shown that the Hall factor in InSb at 77K is less than 1 and decreases with electric field. In the case of vanishing transverse electric field, the longitudinal velocity and the transverse velocity are calculated as a function of the magnetic field and the electric field. The effect of the magnetic field on the longitudinal velocity is different from that on the transverse velocity.
