Hot-Electron Hall Transport inn-Type Germanium

The hot-electron Hall coefficient in $n-\mathrm{G}\mathrm{e}$ is theoretically estimated incorporating the band nonparabolicity, the electron transfer to the $〈100〉$ minima, and the effect of the magnetic field on the distribution function. A better agreement with the nature of the experimental curve at 200 °K is obtained when the nonparabolicity is considered than when it is ignored. A close fit with experiment requires the value of the deformation-potential constants for the optical and for the nonequivalent intervalley scattering to be 0.66 × ${10}^9$ and 0.5 × ${10}^9$ eV ${\mathrm{cm}}^{-1\mathrm{}}$, respectively.
