Optical spin pumping of modulation doped electrons probed by a two-color Kerr rotation technique
H. Hoffmann, G. V. Astakhov, T. Kiessling +5
We report on optical spin pumping of modulation electrons in CdTe-based quantum wells with low intrinsic electron density (by 10^10 cm^{-2}). Under continuous wave excitation, we r…
Engineering of spin-lattice relaxation dynamics by digital growth of diluted magnetic semiconductor CdMnTe
M. K. Kneip, D. R. Yakovlev, M. Bayer +3
The technological concept of "digital alloying" offered by molecular-beam epitaxy is demonstrated to be a very effective tool for tailoring static and dynamic magnetic properties o…
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…
Resonant photoluminescence and excitation spectroscopy of CdSe/ZnSe and CdTe/ZnTe self-assembled quantum dots
T. A. Nguyen, S. Mackowski, H. Rho +8
We show that two major carrier excitation mechanisms are present in II-VI self-assembled quantum dots. The first one is related to direct excited state - ground state transition. I…
Exciton Spin Relaxation Time in Quantum Dots Measured by Continuous-Wave Photoluminescence Spectroscopy
S. Mackowski, T. A. Nguyen, H. E. Jackson +3
We demonstrate a new method of measuring the exciton spin relaxation time in semiconductor nanostructures by continuous-wave photoluminescence. We find that for self-assembled CdTe…
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…
