Abstract
Recent experiments have shown that electrons and holes in normal Ge and Si undergo a gas-liquid-type transition at low temperatures as a function of density. In this paper we present results of numerical calculations of the ground-state energy of an electron-hole liquid for five different cases: i) isotropic electron-hole liquid, ii) Si under a large [100]-strain, iii) Ge under a large [111]-strain, iv) Ge and v) Si, using a self-consistent theory which takes multiple scattering between all components of the quantum plasma into account. Important effects of anisotropy have also been considered. Results of these calculations have been compared with those based on approximations which neglect multiple scattering. Numerical results for the binding energy, equilibrium density, enhancement factors and partial pair correlation functions are presented and discussed in the light of available experimental data.
