We report on the electrical resistivity and thermoelectric power of liquid Si and Ge. The basic ingredients of the calculations are obtained by using a variational procedure based on a third-order perturbation theory. In the calculations we employ an on-Fermi-sphere model potential suitable for these systems. The reference structure factors used in the final calculations are obtained by introducing softness in the hard-sphere description of the structure factors through a scaling procedure. The calculated resistivities and thermoelectric power are comparable to the experimental as well as to the available theoretical results.
