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…
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…
Robust Magnetic Polarons in Type-II (Zn,Mn)Te Quantum Dots
I. R. Sellers, R. Oszwaldowski, V. R. Whiteside +7
We present evidence of magnetic ordering in type-II (Zn, Mn) Te quantum dots. This ordering is attributed to the formation of bound magnetic polarons caused by the exchange interac…
Analytical Model of Spin-Polarized Semiconductor Lasers
Christian Gothgen, Rafal Oszwaldowski, Athos Petrou +1
We formulate an analytical model for vertical-cavity surface-emitting lasers (VCSELs) with injection (pump) of spin-polarized electrons. Our results for two different modes of carr…
Coherent Aharonov Bohm oscillations in type-II (ZnMn)Te quantum dots
I. R. Sellers, V. R. Whiteside, A. O. Govorov +5
The magneto-photoluminescence of type-II (ZnMn)Te quantum dots is presented. As a result of the type-II band alignment Aharonov-Bohm (AB) oscillations in the photoluminescence inte…
Internal transitions of negatively charged magneto-excitons and many body effects in a two-dimensional electron gas
H. A. Nickel, T. M. Yeo, A. B. Dzyubenko +5
Spin-singlet and spin-triplet internal transitions of quasi-two-dimensional, negatively charged magneto-excitons (X-) and their evolution with excess electron density have been stu…
