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…
Doppler velocimetry of spin propagation in a two-dimensional electron gas
Luyi Yang, J. D. Koralek, J. Orenstein +3
Controlling the flow of electrons by manipulation of their spin is a key to the development of spin-based electronics. While recent demonstrations of electrical-gate control in spi…
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…
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…
