POLARON EFFECT IN RESONANT RAMAN-SCATTERING FROM QUANTUM-WELLS IN A HIGH MAGNETIC-FIELD - DECOMPENSATION OF ELECTRON AND HOLE CONTRIBUTIONS

In the framework of a simple model we show that there is no compensation of electron and hole contributions to the intensity of one-phonon resonant Raman scattering in the range of parameters where the incoming or outgoing resonances are split by the Frohlich electron-phonon interaction (magnetopolaron region). The difference in the penetration of electron and hole wave functions into the barrier, usually assumed to account for the nonzero value of the one-phonon scattering intensity, can be considered as a competing (or complementing) mechanism in the magnetopolaron range, depending on the parameters of the quantum-well structure.
