We present analysis of a series of luminescence spectra arising from the electron-hole liquid in germanium under uniaxial compressive stress oriented along the [111] crystallographic axis. We evaluate the groundstate properties of the liquid in the infinite-stress limit using an extrapolation. We find that the electron Fermi energy is reduced from its zero-stress value by a factor of 3.3, the hole Fermi energy by 2.0, and the e-h pair density by 24, in agreement with theoretical predictions.
