Optical absorption to probe the quantum Hall ferromagnet at filling factor
P. Plochocka, J. M. Schneider, D. K. Maude +7
Optical absorption measurements are used to probe the spin polarization in the integer and fractional quantum Hall effect regimes. The system is fully spin polarized only at fillin…

Anisotropy and periodicity in the density distribution of electrons in a quantum-well
Y. Yayon, M. Rappaport, V. Umansky +1
We use low temperature near-field optical spectroscopy to image the electron density distribution in the plane of a high mobility GaAs quantum well. We find that the electrons are…

Near-field spectroscopy of a gated electron gas: a direct evidence for electrons localization
G. Eytan, Y. Yayon, M. Rappaport +2
The near-field photoluminescence of a gated two-dimensional electron gas is measured. We use the negatively charged exciton, formed by binding of an electron to a photo-excited ele…
