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…
Electrical and terahertz magnetospectroscopy studies of laser-patterned micro- and nanostructures on InAs-based heterostructures
Olivio Chiatti, Sven S. Buchholz, Christian Heyn +4
Nanostructures fabricated from narrow-gap semiconductors with strong spin-orbit interaction (SOI), such as InAs, can be used to filter momentum modes of electrons and offer the pos…
Terahertz dynamics of a topologically protected state: quantum Hall effect plateaus near cyclotron resonance in a GaAs/AlGaAs heterojunction
A. V. Stier, C. T. Ellis, H. Zhang +5
We measure the Hall conductivity of a two-dimensional electron gas formed at a GaAs/AlGaAs heterojunction in the terahertz regime close to the cyclotron resonance frequency by empl…
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…
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…
