Exciton-Two-Phonon Raman Scattering of Light in a Quantum Well
Эшпулатов, Б.
Аннотация
The theory of exciton-two-phonon resonant Raman scattering of light in a quantum well has been developed. This article shows that in the case of exciton-two-phonon Raman scattering of light, in which two-dimensional excitons appear as intermediate states, it leads to a sharp increase in scattering compared to the mechanism of electron-hole pairs. The amplification is due to the fact that in a quantum well, in which the energies of the electron and hole are dimensionally quantized, the process of direct creation (or direct annihilation) of an exciton and the actual emission of a second phonon by the exciton are possible. Scattering tensor at the maximum of the second phonon repetition peak.
