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…
Coulomb Drag in the Exciton Regime in Electron-Hole Bilayers
J. A. Seamons, C. P. Morath, J. L. Reno +1
We report electrical transport measurements on GaAs/AlGaAs based electron-hole bilayers. These systems are expected to make a transition from a pair of weakly coupled two-dimension…
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…
Tunneling and nonlinear transport in a vertically coupled GaAs/AlGaAs double quantum wire system
E. Bielejec, J. A. Seamons, J. L. Reno +1
We report low-dimensional tunneling in an independently contacted vertically coupled quantum wire system. This nanostructure is fabricated in a high quality GaAs/AlGaAs parallel do…
