Drift mobility and Hall coefficient factor of holes in germanium and silicon

Abstract

The drift mobility and the Hall coefficient factor are calculated using the Kane band structure model without approximations. Acoustic and optical phonon scattering and also impurity scattering are considered. The effects of light and heavy holes on the drift and the Hall mobility are discussed. The results for the drift mobility agree with experimental data both for Ge and Si. The results for the Hall coefficient factor are in good agreement for Si, but in the case of Ge, the agreement is only fair.
