Optical Study of an Asymmetric Double Quantum Well System: CdTe/CdMnTe

Carrier tunneling through CdMnTe barriers of different thicknesses is investigated in CdTe/CdMnTe asymmetric double quantum wells. Steady-state photoluminescence at 1.8 K and time-resolved photoluminescence experiments between 10 K and 50 K were performed

Time-resolved optical studies of coupling in CdTe/CdMnTe asymmetric double quantum wells

Tunneling in asymmetric double quantum wells (ADQWs) CdTe/CdMnTe where one of the QWs contains Mn is studied for different tunneling barrier thickness. From time-resolved photoluminescence (TRPL) experiments at various temperature up to 80K, tunneling times and radiative lifetimes are extracted
