Suppressed decay of a laterally confined persistent spin helix
P. Altmann, M. P. Walser, C. Reichl +2
We experimentally investigate the dynamics of a persistent spin helix in etched GaAs wire structures of 2 to 80 um width. Using magneto-optical Kerr rotation with high spatial reso…
Dynamics of a localized spin excitation close to the spin-helix regime
G. Salis, M. P. Walser, P. Altmann +2
The time evolution of a local spin excitation in a (001)-confined two-dimensional electron gas subjected to Rashba and Dresselhaus spin-orbit interactions of similar strength is in…
Direct mapping of the formation of a persistent spin helix: Supplementary information
M. P. Walser, C. Reichl, W. Wegscheider +1
The spin-orbit interaction (SOI) in zincblende semiconductor quantum wells can be set to a symmetry point, in which spin decay is strongly suppressed for a helical spin mode. Signa…
Role of linear and cubic terms for the drift-induced Dresselhaus spin-orbit splitting in a two-dimensional electron gas
M. Studer, M. P. Walser, S. Baer +6
The Dresselhaus spin-orbit interaction (SOI) of a series of two-dimensional electron gases (2DEGs) hosted in GaAs/AlGaAs and InGaAs/GaAs (001) quantum wells (QWs) is measured by mo…
