Density imbalance effect on the Coulomb drag upturn in an electron-hole bialyer
Christian P. Morath, John A. Seamons, John L. Reno +1
A low-temperature upturn of the Coulomb drag resistivity measured in an undoped electron-hole bilayer (uEHBL) device, possibly manifesting from exciton formation or condensation, w…
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…
Layer interdependence of transport in an undoped electron-hole bilayer
C. P. Morath, J. A. Seamons, J. L. Reno +1
The layer interdependence of transport in an undoped electron-hole bilayer (uEHBL) device was studied as a function of carrier density, interlayer electric field, and temperature.…
Undoped Electron-Hole Bilayers in a GaAs/AlGaAs Double Quantum Well
J. A. Seamons, D. R. Tibbetts, J. L. Reno +1
We present the fabrication details of completely undoped electron-hole bilayer devices in a GaAs/AlGaAs double quantum well heterostructure with a 30 nm barrier. These devices have…
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}…
Excitonic condensate and quasiparticle transport in electron-hole bilayer systems
Yogesh N. Joglekar, Alexander V. Balatsky, Michael P. Lilly
Bilayer electron-hole systems undergo excitonic condensation when the distance d between the layers is smaller than the typical distance between particles within a layer. All excit…
