Deformation potentials are calculated for electron‐hole droplets in Ge and compared to the values for degenerate n‐ or p‐doped Ge. Due to the conduction band anisotropy and the presence of an equal number of electrons and holes, it is found that screening effects are substantially reduced, but that there are strong anisotropies in coupling to various phonon modes.
