Charged exctions in the fractional quantum Hall regime
G. Yusa, H. Shtrikman, I. Bar-Joseph
We study the photoluminescence spectrum of a low density () two-dimensional electron gas at high magnetic fields and low temperatures. We find that the spectrum in the fractio…
Abrupt Transition between Thermally-Activated Relaxation and Quantum Tunneling in a Molecular Magnet
K. M. Mertes, Y. Zhong, M. P. Sarachik +5
We report Hall sensor measurements of the magnetic relaxation of Mn acetate as a function of magnetic field applied along the easy axis of magnetization. Data taken at a ser…
The onset of exciton absorption in modulation doped GaAs quantum wells
G. Yusa, H. Shtrikman, I. Bar-Joseph
We study the evolution of the absorption spectrum of a modulation doped GaAs/AlGaAs semiconductor quantum well with decreasing the carrier density. We find that there is a critical…
Surface barrier dominated transport in NbSe
Y. Paltiel, D. T. Fuchs, E. Zeldov +3
Transport current distribution in clean 2-NbSe crystals is studied by measuring the self-induced magnetic field across the sample. Below most of the current flows at…
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…
Inductive Probing of the Integer Quantum Hall Effect
Eyal Yahel, Dror Orgad, Alexander Palevski +1
We investigated the Integer Quantum Hall Effect (IQHE) using an inductive method. The following conclusions can be derived from our study: (i) when the Fermi energy is located betw…
