Drift velocity for holes in high-purity Ge ($|{N}_{D}\ensuremath{-}{N}_{A}|l{10}^{11}$ ${\mathrm{cm}}^{\ensuremath{-}3}$) has been analyzed for a wide range of temperatures $8\ensuremath{\le}T\ensuremath{\le}220$ \ifmmode^\circ\else\textdegree\fi{}K and fields $1\ensuremath{\le}E\ensuremath{\le}{10}^{4}$ V/cm applied parallel to 100g, 110g, and 111g crystallographic directions. Experiments are carried out with the time-of-flight technique and theory uses a Monte Carlo method. The physical model includes warping and nonparabolic effect of the heavy-hole band, as well as acoustic and non-polar optical scattering mechanisms. In the case of the acoustic scattering mechanism, energy dissipation and the correct phonon population have been included.
