The Observation of Percolation-Induced 2D Metal-Insulator Transition in a Si MOSFET
L. A. Tracy, E. H. Hwang, K. Eng +6
By analyzing the temperature () and density () dependence of the measured conductivity () of 2D electrons in the low density (cm) and temperature (0.02…
Spin Transition in the Half-Filled Landau Level
L. A. Tracy, J. P. Eisenstein, L. N. Pfeiffer +1
The transition from partial to complete spin polarization of two-dimensional electrons at half filling of the lowest Landau level has been studied using resistively-detected nuclea…
Resistively-Detected NMR in a Two-Dimensional Electron System near : Clues to the Origin of the Dispersive Lineshape
L. A. Tracy, J. P. Eisenstein, L. N. Pfeiffer +1
Resistively-detected NMR measurements on 2D electron systems near the quantum Hall state are reported. In contrast to recent results of Gervais \emph{et al.} [Phys. Rev. Let…
Surface Acoustic Wave Propagation and Inhomogeneities in Low Density Two-Dimensional Electron Systems Near the Metal-Insulator Transition
L. A. Tracy, J. P. Eisenstein, M. P. Lilly +2
We have measured the surface acoustic wave velocity shift in a GaAs/AlGaAs heterostructure containing a two-dimensional electron system (2DES) in a low-density regime ( $10^{10}…
Spin Transition in Strongly Correlated Bilayer Two Dimensional Electron Systems
I. B. Spielman, L. A. Tracy, J. P. Eisenstein +2
Using a combination of heat pulse and nuclear magnetic resonance techniques we demonstrate that the phase boundary separating the interlayer phase coherent quantum Hall effect at $…
Carrier relaxation dynamics in heavy fermion compounds
J. Demsar, L. A. Tracy, R. D. Averitt +3
The first femtosecond carrier relaxation dynamics studies in heavy fermion compounds are presented. The carrier relaxation time shows a dramatic hundred-fold increase below the Kon…
