Spin Susceptibility of a 2D Electron System in GaAs towards the Weak Interaction Region
Y. -W. Tan, J. Zhu, H. L. Stormer +3
We determine the spin susceptibility in the weak interaction regime of a tunable, high quality, two-dimensional electron system in a GaAs/AlGaAs heterostructure. The band struc…
Measurements of the density-dependent many-body electron mass in 2D GaAs/AlGaAs Heterostructures
Y. -W. Tan, J. Zhu, H. L. Stormer +3
We determine the density-dependent electron mass, m*, in two-dimensional (2D) electron systems of GaAs/AlGaAs heterostructures by performing detailed low-temperature Shubnikov deHa…
2D Metal-Insulator transition as a percolation transition
S. Das Sarma, M. P. Lilly, E. H. Hwang +3
By carefully analyzing the low temperature density dependence of 2D conductivity in undoped high mobility n-GaAs heterostructures, we conclude that the 2D metal-insulator transitio…
Measurements of Gated Conjugated Polymer with Electrode Spacing Down to Several Nanometers
David Abusch-Magder, Takao Someya, James Wang +4
In this letter we describe electronic measurements of a conjugated polymer of phenylenevinylene (PPV) with electrode spacings down to 20 nm; all measurements are made in a gated tr…
Evidence for a Goldstone Mode in a Double Layer Quantum Hall System
I. B. Spielman, J. P. Eisenstein, L. N. Pfeiffer +1
The tunneling conductance between two parallel 2D electron systems has been measured in a regime of strong interlayer Coulomb correlations. At total Landau level filling th…
Enhancement of Coulomb drag away from half filled Landau levels
M. P. Lilly, J. P. Eisenstein, L. N. Pfeiffer +1
Coulomb drag between two parallel two dimensional electron gases has been measured at high magnetic fields in samples with two different layer spacings. As the layer filling factor…
