Spin drift and diffusion in one- and two-subband helical systems
Gerson J. Ferreira, Felix G. G. Hernandez, Patrick Altmann +1
The theory of spin drift and diffusion in two-dimensional electron gases is developed in terms of a random walk model incorporating Rashba, linear and cubic Dresselhaus, and inters…

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…
