Effect of initial spin polarization on spin dephasing and electron g factor in a high-mobility two-dimensional electron system
D. Stich, J. Zhou, T. Korn +4
We have investigated the spin dynamics of a high-mobility two-dimensional electron system (2DES) in a GaAs--AlGaAs single quantum well by time-resolved Faraday rota…
Rashba and Dresselhaus Spin-Splittings in Semiconductor Quantum Wells Measured by Spin Photocurrents
S. Giglberger, L. E. Golub, V. V. Bel'kov +9
The spin-galvanic effect and the circular photogalvanic effect induced by terahertz radiation are applied to determine the relative strengths of Rashba and Dresselhaus band spin-sp…
Bias dependent inversion of tunneling magnetoresistance in Fe/GaAs/Fe tunnel junctions
J. Moser, M. Zenger, C. Gerl +10
We investigated spin dependent transport through Fe/GaAs/Fe tunnel junctions. The tunneling magnetoresistance effect (TMR) was probed for different types of Fe/GaAs interfaces. For…
Vertical quantum wire realized with double cleaved-edge overgrowth
S. F. Roth, H. J. Krenner, D. Schuh +2
A quantum wire is fabricated on (001)-GaAs at the intersection of two overgrown cleaves. The wire is contacted at each end to n+ GaAs layers via two-dimensional (2D) leads. A sideg…
Drift mobility of long-living excitons in coupled GaAs quantum wells
A. Gartner, A. W. Holleitner, D. Schuh +1
We observe high-mobility transport of indirect excitons in coupled GaAs quantum wells. A voltage-tunable in-plane potential gradient is defined for excitons by exploiting the quant…
