Magnetic polaron formation and exciton spin relaxation in single CdMnTe quantum dots
Łukasz Kłopotowski, Łukasz Cywiński, Piotr Wojnar +8
We study the formation dynamics of a spontaneous ferromagnetic order in single self-assembled CdMnTe quantum dots. By measuring time-resolved photoluminescence, we determine the fo…
0.7-anomaly and magnetotransport of disordered quantum wires
M. Czapkiewicz, P. Zagrajek, J. Wrobel +6
The unexpected "0.7" plateau of conductance quantisation is usually observed for ballistic one-dimensional devices. In this work we study a quasi-ballistic quantum wire, for which…
Spin filtering in a hybrid ferromagnetic-semiconductor microstructure
J. Wróbel, T. Dietl, A. Lusakowski +5
We fabricated a hybrid structure in which cobalt and permalloy micromagnets produce a local in-plane spin-dependent potential barrier for high-mobility electrons at the GaAs/AlGaAs…
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 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…
