Influence of the single-particle Zeeman energy on the quantum Hall ferromagnet at high filling factors
B. A. Piot, D. K. Maude, M. Henini +10
In a recent paper [B. A. Piot et al., Phys. Rev. B 72, 245325 (2005)], we have shown that the lifting of the electron spin degeneracy in the integer quantum Hall effect at high fil…
Frequency quenching of microwave induced resistance oscillations in a high mobility two-dimensional electron gas
S. A. Studenikin, A. S. Sachrajda, J. A. Gupta +8
The frequency dependence of microwave-induced resistance oscillations (MIROs) has been studied experimentally in high-mobility electron GaAs/AlGaAs structures to explore the limits…
The quantum Hall ferromagnet at high filling factors: A magnetic field induced Stoner transition
B. A. Piot, D. K. Maude, M. Henini +7
Spin splitting in the integer quantum Hall effect is investigated for a series of AlGaAs/GaAs heterojunctions and quantum wells. Magnetoresistance measurements are pe…
The microwave induced resistance response of a high mobility 2DEG from the quasi-classical limit to the quantum Hall regime
S. A. Studenikin, M. Byszewski, D. K. Maude +6
Microwave induced resistance oscillations (MIROs) were studied experimentally over a very wide range of frequencies ranging from ~20 GHz up to ~4 THz, and from the quasi-classical…
Exciton lifetime in InAs/GaAs quantum dot molecules
C. Bardot, M. Schwab, M. Bayer +3
The exciton lifetimes in arrays of InAs/GaAs vertically coupled quantum dot pairs have been measured by time-resolved photoluminescence. A considerable reduction of by…
Non-linear exciton spin-splitting in single InAs/GaAs self-assembled quantum structures in ultrahigh magnetic fields
A. Babinski, G. Ortner, S. Raymond +6
We report on the magnetic field dispersion of the exciton spin-splitting and diamagnetic shift in single InAs/GaAs quantum dots (QDs) and dot molecules (QDMs) up to = 28 T. Onl…
