Surface polaritons and Brewster waves in the exciton luminescence spectra
Agranovich V.M., Leskova T.A.
We show that surface polaritons (SP), after scattering on phonons and surface irregularities, produce two peaks in the exciton luminescence spectra in the region of the longitudinal-transverse splitting. We also noticed a presence of the "narrow-neck" effect for SP and the angular distribution of low-temperature luminescence associated with the Brewster waves.
