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…
IV-VI resonant cavity enhanced photodetectors for the midinfrared
M. Boeberl, T. Fromherz, T. Schwarzl +2
A resonant-cavity enhanced detector operating in the mid-infrared at a wavelength around 3.6 micron is demonstrated. The device is based on a narrow-gap lead salt heterostructure g…
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…
Tuning the properties of magnetic CdMnTe quantum dots
S. Mackowski, H. E. Jackson, L. M. Smith +3
We show that CdMnTe self-assembled quantum dots can be formed by depositing a submonolayer of Mn ions over a ZnTe surface prior to deposition of the CdTe dot layer. Single dot emis…
