Effect of impurity scattering on the hole drift velocity in germanium

The effect of the impurity-scattering mechanism on the hole drift velocity in Ge is studied for impurity concentration $N_I\le {10}^{17}$ ${\mathrm{cm}}^{-3\mathrm{}}$ at 77 and 300 K. Results, which account for warping and nonparabolic effects of the heavy-hole band, complete an analysis previously published.
