Acousto-electric study of microwave-induced current domains
Benedikt Friess, Ivan A. Dmitriev, Vladimir Umansky +4
Surface Acoustic Waves (SAW) have been utilized to investigate the properties of a two-dimensional electron system, subjected to a perpendicular magnetic field and monochromatic mi…
Characterization of individual layers in a bilayer electron system produced in a wide quantum well
S. I. Dorozhkin, A. A. Kapustin, I. B. Fedorov +3
Here we report on a transparent method to characterize individual layers in a double-layer electron system which forms in a wide quantum well and to determine their electron densit…
Hall field-induced resistance oscillations in a tunable-density GaAs quantum well
M. A. Zudov, Q. Shi, I. A. Dmitriev +4
We report on Hall field-induced resistance oscillations (HIRO) in a 60 nm-wide GaAs/AlGaAs quantum well with an \emph{in situ} grown back gate, which allows tuning the carrier dens…
Apparent temperature-induced reorientation of quantum Hall stripes
Q. Shi, M. A. Zudov, B. Friess +4
Our magnetotransport measurements of quantum Hall stripes in a high-quality GaAs quantum well in a slightly tilted magnetic field reveal that the orientation of stripes can be chan…
Fine structure of high-power microwave-induced resistance oscillations
Q. Shi, M. A. Zudov, I. A. Dmitriev +3
We report on observation of a fine structure of microwave-induced resistance oscillations in an ultraclean two-dimensional electron gas. This fine structure is manifested by multip…
Microwave-Induced Oscillations in the Magnetocapacitance: Direct Evidence for Non-equilibrium Occupation of Electronic States
S. I. Dorozhkin, A. A. Kapustin, V. Umansky +2
In a two-dimensional electron system, microwave radiation may induce giant resistance oscillations. Their origin has been debated controversially and numerous mechanisms based on v…
