| Abstract: | The properties of an electron-hole liquid with different densities of spin-up and spin-down carriers have been calculated for a simple semiconductor model and CdS. The spin polarization lowers both equilibrium density and binding energy. Exchange leads to a different energy gap for each spin direction which can be detected in the circular polarization of the luminescence. |
