Abstract

One‐LO‐phonon resonant Raman scattering in quantum wells in the presence of the magneto‐polaron effect was investigated theoretically. The cross‐section of Raman scattering involving uncorrelated electron–hole pairs as intermediate states was calculated using the parabolic model of valence bands. An analysis showed that the magneto‐polaron effect plays an important role in double‐resonant Raman processes. The Raman intensity under double‐resonant conditions in a magnetic field is strongly increased by α^−1^ times, where α is the electron–phonon coupling constant. The Fröhlich and deformation‐potential electron–phonon interactions are considered for different scattering configurations in a model of confined phonons.
