For single crystal of n-type Ge with orientation (110), the relation of magneto-resistance in weak field with respect to magnetic intensity in range 0-7000 gauss and temperature variation are measured. Hall' effect and conductivity are also studied experimentally.Neglecting magnetic intensity higher than quadratic terms, various parameters in phenomenological formula for cubic symmetry crystal are calculated...

Experimental method of measuring magneto-resistance and it's relationship with band structure are discussed. For single crystal of n-type Ge with orientation (110), the relation of magneto-resistance in weak field with respect to magnetic intensity in range 0-7000 gauss and temperature variation are measured. Hall' effect and conductivity are also studied experimentally.Neglecting magnetic intensity higher than quadratic terms, various parameters in phenomenological formula for cubic symmetry crystal are calculated from our experimental data. Our results indicate that the energy valley of conduction band of Ge is not lying in the center of Brillouin zone and the constant energy surface possesses non-spherical symmetry.

The effect of a uniform electric field upon the distribution function of carriers in a single energy valley semiconductor is discussed. By using the concept of mcan free path and assuming that the carriers follow the Boltzmann distribution and taking into account the classical statistics of non-degenerated carriers, a concise expression for a drift velocity under arbitrary electric field has been derived. The curve for this expression agrees very well with that from known experiments.
