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 Magneto Optical Polarization Modulation Spectroscopy
D. K. George, A. V. Stier, C. T. Ellis +3
We report the development of new terahertz techniques for rapidly measuring the complex Faraday angle in systems with broken time-reversal symmetry using the cyclotron resonance of…
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…
