The Kadanoff-Baym Green-function formalism is used to calculate the heavy- and light-hole mobilities in p-type ${\mathrm{Hg}}_{1\mathrm{-}\mathit{x}}$${\mathrm{Cd}}_{\mathit{x}}$Te (x=0.2). The polar-optical-phonon and charged-impurity scatterings are included in the self-consistent Born approximation. A comparison with a Boltzmann-equation calculation is made. Significant corrections are found.
