Photo-excited semiconductor superlattices as constrained excitable media: Motion of dipole domains and current self-oscillations
J. I. Arana, L. L. Bonilla, H. T. Grahn
A model for charge transport in undoped, photo-excited semiconductor superlattices, which includes the dependence of the electron-hole recombination on the electric field and on th…
Quantum effects in linear and non-linear transport of T-shaped ballistic junction
J. Wrobel, P. Zagrajek, M. Czapkiewicz +6
We report low-temperature transport measurements of three-terminal T-shaped device patterned from GaAs/AlGaAs heterostructure. We demonstrate the mode branching and bend resistance…
Parquet theory for correlated thermodynamic Greens functions
P. Kleinert
We address the problem of finding self-consistent parquet equations for two-body correlated Greens functions that arise out of a cumulant expansion. The general theory as developed…
Measurement of the infrared transmission through a single doped GaAs quantum well in an external magnetic field: Evidence for polaron effects
C. Faugeras, M. Orlita, S. Deutschlander +5
Precise absolute far-infra-red magneto-transmission experiments have been performed in magnetic fields up to 33 T on a series of single GaAs quantum wells doped at different levels…
Phase study of oscillatory resistances in microwave-irradiated- and dark- GaAs/AlGaAs devices: Indications of a new class of integral quantum Hall effect
R. G. Mani, W. B. Johnson, V. Umansky +2
We report the experimental results from a dark study and a photo-excited study of the high mobility GaAs/AlGaAs system at large filling factors, . At large-, the dark study i…
Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
K. -J. Friedland, A. Siddiki, R. Hey +3
The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. The novel topology leads to a spatially varying filling factor…
