Abstract
We report the study of the effect of miniband width on polarization properties of the hot electron photoluminescence (HPL) in SLs . It is demonstrated that the energy and magnetic field dependencies of the HPL polarization are very sensitive to the electron miniband widths. We show that high magnetic field applied perpendicular to the SL growth direction (Voigt geometry) induces transition (magnetic field breakdown) between electron minibands. The vertical transport of spin polarized and momentum aligned hot electrons is studied.
