Observing Spin Polarization of Individual Magnetic Adatoms
Y. Yayon, V. W. Brar, L. Senapati +2
We have used spin-polarized scanning tunneling spectroscopy to observe the spin-polarization state of individual Fe and Cr atoms adsorbed onto Co nanoislands. Both of these magneti…
Long-range spatial correlations in the exciton energy distribution in GaAs/AlGaAs quantum-wells
Y. Yayon, A. Esser, M. Rappaport +3
Variations in the width of a quantum well (QW) are known to be a source of broadening of the exciton line. Using low temperature near-field optical microscopy, we have exploited th…
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…
Excitonic emission in the presence of a two dimensional electron gas: a microscopic understanding
Y. Yayon, M. Rappaport, V. Umansky +1
The near- and far-field photoluminescence spectra of a gated two-dimensional electron gas have been measured. Spatial fluctuations in the electron density are found to be manifeste…
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…
