| Abstract: | Emission spectra of high-purity GaAs have been studied at 4.2 K under N2 laser excitation. The slope of the low-energy tail of the main band has been found to fit well with the theoretical prediction for radiative Auger recombination of free excitons. Measurements under electric field support the dominant contribution of this process in the luminescence of highly excited GaAs. |
