Circular polarization of recombination radiation of silicon in a magnetic field at a high excitation level
Altukhov P.O., Pikus G.E., Rogachev A.A.
We investigated the circular polarization of the emission line with maximum energy 1.082 eV and the emission lines of free and bound excitons in silicon in magnetic fields up to 50 kOe in the temperature interval 1.9-15°K. The polarization of the 1.082-eV line exceeds by more than one order of magnitude the value expected in the simple exciton-condensate model.
