The size of small electron-hole drops near threshold is investigated in Ge using a small shift of their main luminescence line due to their surface energy σ. The smallest radii measured at different temperatures are compared with the minimum stable radii given by a model taking σ and the drop binding energy φ into account. We find an excellent agreement if we use the spectroscopic value of φ (23 K).
