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…
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…
Resonant and non-resonant PL and PLE spectra of CdSe/ZnSe and CdTe/ZnTe self-assembled quantum dots
T. A. Nguyen, S. Mackowski, L. M. Robinson +6
Using micro- and nano-scale resonantly excited PL and PLE, we study the excitonic structure of CdSe/ZnSe and CdTe/ZnTe self assembled quantum dots (SAQD). Strong resonantly enhance…
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…
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…
