Coherent Propagation of Spin Helices in a Quantum-Well Confined Electron Gas
Luyi Yang, J. D. Koralek, J. Orenstein +3
We use phase-resolved transient grating spectroscopy to measure the propagation of spin helices in a high mobility -GaAs/AlGaAs quantum well with an applied in-plane electric fi…
Measurement of electron-hole friction in an n-doped GaAs/AlGaAs quantum well using optical transient grating spectroscopy
Luyi Yang, J. D. Koralek, J. Orenstein +3
We use phase-resolved transient grating spectroscopy to measure the drift and diffusion of electron-hole density waves in a semiconductor quantum well. The unique aspects of this o…
Observation of Chiral Heat Transport in the Quantum Hall Regime
G. Granger, J. P. Eisenstein, J. L. Reno
Heat transport in the quantum Hall regime is investigated using micron-scale heaters and thermometers positioned along the edge of a millimeter-scale two dimensional electron syste…
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…
Probing the microscopic structure of bound states in quantum point contacts
Y. Yoon, L. Mourokh, T. Morimoto +4
Using an approach that allows us to probe the electronic structure of strongly pinched-off quantum point contacts (QPCs), we provide evidence for the formation of self-consistently…
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…
