The allowed exciton transitions n = 1, 2, 3 were revealed in the reflection spectra of ZnAs2 monocrystals at 10K. Transverse and longitudinal exciton energies, longitudinal splitting value, translation and reduced exciton masses, electron and hole effective masses were revealed from fitting of the exciton spectra. Absorption spectra and absorption interference were studied for E || c and E ⊥ c polarizations for thin samples. The polariton branches of exciton polaritons were calculated from the experimental results. |
