Optical Gain from InAs Nanocrystal Quantum Dots in a Polymer Matrix
Gang Chen, Ronen Rapaport, Dan Fuchs +3
We report on the first observation of optical gain from InAs nanocrystal quantum dots emitting at 1.55 microns based on a three-beam, time resolved pump-probe technique. The nanocr…
Optical manipulation of nuclear spin by a two-dimensional electron gas
G. Salis, D. T. Fuchs, J. M. Kikkawa +3
Conduction electrons are used to optically polarize, detect and manipulate nuclear spin in a (110) GaAs quantum well. Using optical Larmor magnetometry, we find that nuclear spin c…
Shear-induced vortex decoupling in Bi2Sr2CaCu2O8 crystals
B. Khaykovich, D. T. Fuchs, K. Teitelbaum +6
Simultaneous transport and magnetization studies in Bi2Sr2CaCu2O8 crystals at elevated currents reveal large discrepancies, including finite resistivity at temperatures of 40K belo…
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…
Transport properties of BSCCO crystals with and without surface barriers
Dan T. Fuchs, Richard A. Doyle, Eli Zeldov +5
Large BSCCO crystals with electrical contacts positioned far from the edges are studied by transport measurements, then cut into the common narrow strip geometry, and remeasured. I…
Possible new vortex matter phases in BSCCO
Dan T. Fuchs, Eli Zeldov, Tsuyoshi Tamegai +3
The vortex matter phase diagram of BSCCO crystals is analyzed by investigating vortex penetration through the surface barrier in the presence of a transport current. The strength o…
