Electrical Detection of Spin Transport in Lateral Ferromagnet-Semiconductor Devices
X. Lou, C. Adelmann, S. A. Crooker +6
A longstanding goal of research in semiconductor spintronics is the ability to inject, modulate, and detect electron spin in a single device. A simple prototype consists of a later…
Tuning alloy disorder in diluted magnetic semiconductors in high fields to 89 T
S. A. Crooker, N. Samarth
Alloy disorder in II-VI diluted magnetic semiconductors (DMS) is typically reduced when the local magnetic spins align in an applied magnetic field. An important and untested expec…
Optical and electrical spin injection and spin transport in hybrid Fe/GaAs devices
S. A. Crooker, M. Furis, X. Lou +4
We discuss methods for imaging the nonequilibrium spin polarization of electrons in Fe/GaAs spin transport devices. Both optically- and electrically-injected spin distributions are…
Low temperature terahertz spectroscopy of n-InSb through a magnetic field driven metal-insulator transition
X. P. A. Gao, J. Y. Sohn, S. A. Crooker
We use fiber-coupled photoconductive emitters and detectors to perform terahertz (THz) spectroscopy of lightly-doped n-InSb directly in the cryogenic (1.5 K) bore of a high-field s…
Electrical Detection of Spin Accumulation at a Ferromagnet-Semiconductor Interface
X. Lou, C. Adelmann, M. Furis +3
We show that the accumulation of spin-polarized electrons at a forward-biased Schottky tunnel barrier between Fe and n-GaAs can be detected electrically. The spin accumulation lead…
