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…

Spin incoherent transport in density-modulated quantum wires
K. M. Liu, H. I. Lin, V. Umansky +1
Density, temperature and magnetic field dependences on electron transport in a quantum wire were studied. Decrease of carrier density gives a negative conductance correction on the…

Absorption in the fractional quantum Hall regime: trion dichroism and spin polarization
J. G. Groshaus, P. Plochocka-Polack, M. Rappaport +7
We present measurements of optical interband absorption in the fractional quantum Hall regime in a GaAs quantum well in the range 0 < nu < 1. We investigate the mechanism of single…
