| Popis: | Optical spectra of low-density exciton gas in a quasi-one-dimensional (q1D) semiconductor are investigated by solving self-consistently an effective Wannier equation which describes an optically created exciton embedded in the exciton gas. It turned out that the onset energy of the continuum states depends only weakly on the exciton density in the low-density regime. The exciton binding energy seems to be finite even in the high-density regime. |
