The potential of Rutherford Backscattering Spectrometry for composition analysis of colloidal nanocrystals
Daniel Primetzhofer, Mikhailo Sytnyk, Paul Joachim Wagner +2
We investigate the potential of elastic scattering of energetic ions for compositional analysis of magnetic colloidal nanocrystals. Thin layers of nanocrystals deposited by spin co…
Exchange interactions in europium monochalcogenide magnetic semiconductors and their dependence on hydrostatic strain
W. Söllinger, W. Heiss, R. T. Lechner +4
The classical Heisenberg model is applied in a Monte Carlo study to investigate the distance dependence of the indirect nearest neighbor (NN) exchange and next-nearest neighbor (NN…
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…
