Gn. Aliev et al., LO-phonon assisted tunneling from spatially direct to indirect exciton in semimagnetic double quantum well structures, PHYSICA E, 10(4), 2001, pp. 511-517
Relaxation from spatially direct to the spatially indirect exciton through
ZnSe barriers of different thicknesses is investigated in (ZnCdMn)Se/ZnSe/(
ZnCd)Se asymmetric double quantum wells by use of magneto-optical steady-st
ate photoluminescence (PL) and PL excitation (PLE) experiments. The I-LO-ph
onon scattering has been found to be the relevant mechanism for effective e
lectron and hole tunneling. (C) 2001 Elsevier Science B.V. All rights reser
