✦ Synopsis

Relaxation from spatially direct to the spatially indirect exciton through ZnSe barriers of di erent thicknesses is investigated in (ZnCdMn)Se=ZnSe=(ZnCd)Se asymmetric double quantum wells by use of magneto-optical steady-state photoluminescence (PL) and PL excitation (PLE) experiments. The 1-LO-phonon scattering has been found to be the relevant mechanism for e ective electron and hole tunneling.
