Optical control of carrier wavefunction in magnetic quantum dots
P. Zhang, T. Norden, J. M. Pientka +10
Spatially indirect Type-II band alignment in magnetically-doped quantum dot (QD) structures provides unexplored opportunities to control the magnetic interaction between carrier wa…
Multiband Electronic Structure of Magnetic Quantum Dots: Numerical Studies
D. Rederth, R. Oszwaldowski, A. G. Petukhov +1
Semiconductor quantum dots (QDs) doped with magnetic impurities have been a focus of continuous research for a couple of decades. A significant effort has been devoted to studies o…
Fermi level position, Coulomb gap, and Dresselhaus splitting in (Ga,Mn)As
S. Souma, L. Chen, R. Oszwaldowski +5
Carrier-induced nature of ferromagnetism in a ferromagnetic semiconductor, (Ga,Mn)As, offers a great opportunity to observe novel spin-related phenomena as well as to demonstrate n…
Time-resolved magnetophotoluminescence studies of magnetic polaron dynamics in type-II quantum dots
B. Barman, R. Oszwałdowski, L. Schweidenback +12
We used continuous wave photoluminescence (cw-PL) and time resolved photoluminescence (TR-PL) spectroscopy to compare the properties of magnetic polarons (MP) in two related spatia…
Reentrant Formation of Magnetic Polarons in Quantum Dots
J. M. Pientka, R. Oszwałdowski, A. G. Petukhov +2
We propose a model of magnetic polaron formation in semiconductor quantum dots doped with magnetic ions. A wetting layer serves as a reservoir of photo-generated holes, which can b…
Spin ordering in magnetic quantum dots: From core-halo to Wigner molecules
R. Oszwałdowski, P. Stano, A. G. Petukhov +1
The interplay of confinement and Coulomb interactions in quantum dots can lead to strongly correlated phases differing qualitatively from the Fermi liquid behavior. We explore how…
