Abstract
Strong resonant-polaron-coupling phenomena in the magnetophotoluminescence (magneto-PL) spectra of modulation-doped quantum wells are reported. The polaron interactions arise between hole quasiparticles in otherwise filled electron Landau levels, and LO phonons of the quantum-well material. This type of many-body polaron-coupling phenomenon is expected to be a universal feature of the magneto-PL spectra of quantum wells with electron Fermi energy greater than the LO-phonon energy of the well material.Keywords
