Measurements of the luminescence from intrinsic Ge, with a nearly uniform photoexcited carrier density, indicate the presence of trions, molecules and excitons at temperatures between 5.5 K and 15 K. We do not observe an ionization catastrophe at densities above the Mott criterion -- an observation which suggests large quantum corrections to the Debye-Huckel screening model.
