摘要：

Raman scattering from a selectively doped n-AlxGa1-xAs/InyGa1-yAs/GaAs single quantum well (QW) has been studied in magnetic fields H<9T. The resonant Raman intensities are found to depend strongly on the magnetic field strength and direction for both electronic excitation and, especially, one-LO-phonon scattering. A mixing of the magnetic field-and QW-induced levels is supposed to be responsible for the change in Raman intensities for magnetic field parallel to the QW plane. © 1991.
