Spin polarization control by electric stirring: proposal for a spintronic device
Yu. V. Pershin, N. A. Sinitsyn, A. Kogan +2
We propose a spintronic device to generate spin polarization in a mesoscopic region by purely electric means. We show that the spin Hall effect in combination with the stirring eff…
Bias-controlled sensitivity of ferromagnet/semiconductor electrical spin detectors
S. A. Crooker, E. Garlid, A. N. Chantis +6
Using Fe/GaAs Schottky tunnel barriers as electrical spin detectors, we show that the magnitude and sign of their spin-detection sensitivities can be widely tuned with the voltage…
Effect of Intra-molecular Disorder and Inter-molecular Electronic Interactions on the Electronic Structure of Poly-p-Phenylene Vinylene (PPV)
Ping Yang, Enrique R. Batista, Sergei Tretiak +3
We investigate the role of intra-molecular conformational disorder and inter-molecular electronic interactions on the electronic structure of disorder clusters of poly-p-phenylene…
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…
Bias-dependent electron spin lifetimes in n-GaAs and the role of donor impact ionization
M. Furis, D. L. Smith, J. L. Reno +1
In bulk n-GaAs epilayers doped near the metal-insulator transition, we study the evolution of electron spin lifetime as a function of applied lateral electrical bias . $…
Persistent spin currents induced by a spatially-dependent magnetic field in a spin-1/2 Heisenberg antiferromagnetic ring
D. Schmeltzer, A. Saxena, A. R. Bishop +1
We show that a spatially-dependent magnetic field can induce a persistent spin current in a spin-1/2 Heisenberg antiferromagnetic ring, proportional to the solid angle subtended by…
