Abstract
The free-exciton luminescence line shape in germanium has been measured as a function of crystal temperature and free-exciton density. In order to fit these data, the theory includes nonparabolicity effects, collision broadening, and Gaussian broadening. From this fit, the bottom of the free-exciton band is at 712.8 ± 0.1 meV and the electron-hole droplet binding energy is 1.9 ± 0.2 meV.Keywords
