Polarization of hot photoluminescence in semiconductors of the GaAs type
Zemskii V.I., Zakharchenya B.P., Mirlin D.N.
We investigate the frequency and polarization dependences of the photoluminescence of hot electrons in semiconductors of the GaAs type. The anomalously large degree of circular polarization and the appearance of linear polarization in the recombination-radiation spectrum are interpreted with account taken of the onset of anisotropy in the momentum distribution when the electrons are photoexcited.
