Optical Orientation of Excitons in CdSe Self-Assembled Quantum Dots
S. Mackowski, T. Gurung, H. E. Jackson +3
We study spin dynamics of excitons confined in self-assembled CdSe quantum dots by means of optical orientation in magnetic field. At zero field the exciton emission from QDs popul…
Sensitivity of Exciton Spin Relaxation in Quantum Dots to Confining Potential
S. Mackowski, T. Gurung, H. E. Jackson +4
We observe a strong dependence of the exciton spin relaxation in CdTe quantum dots on the average dot size and the depth of the confining potential. For the excitons confined to th…
Optical Studies of Zero-Field Magnetization of CdMnTe Quantum Dots: Influence of Average Size and Composition of Quantum Dots
T. Gurung, S. Mackowski, H. E. Jackson +4
We show that through the resonant optical excitation of spin-polarized excitons into CdMnTe magnetic quantum dots, we can induce a macroscopic magnetization of the Mn impurities. W…
Optically Induced Magnetization of CdMnTe Self-Assembled Quantum Dots
S. Mackowski, T. Gurung, T. A. Nguyen +4
We demonstrate that resonant excitation of CdMnTe self-assembled quantum dots creates an ensemble of spin-polarized magnetic polarons at B=0 T. The strong spatial confinement chara…
Exciton spin relaxation in resonantly excited CdTe/ZnTe self-assembled quantum dots
S. Mackowski, T. A. Nguyen, T. Gurung +7
We study the exciton spin relaxation in CdTe self-assembled quantum dots by using polarized photoluminescence spectroscopy in magnetic field. The experiments on single CdTe quantum…
