Direct observation of intravalley spin relaxation in single-layer WS
Z. Wang, A. Molina-Sanchez, P. Altmann +12
In monolayer Transition Metal Dichalcogenides (TMDs) the valence and conduction bands are spin split because of the strong spin-orbit interaction. In tungsten-based TMDs the spin-o…
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…
Current-controlled Spin Precession of Quasi-Stationary Electrons in a Cubic Spin-Orbit Field
P. Altmann, F. G. G. Hernandez, G. J. Ferreira +4
Space- and time-resolved measurements of spin drift and diffusion are performed on a GaAs-hosted two-dimensional electron gas. For spins where forward drift is compensated by backw…
Transition of a 2D spin mode to a helical state by lateral confinement
P. Altmann, M. Kohda, C. Reichl +2
Spin-orbit interaction (SOI) leads to spin precession about a momentum-dependent spin-orbit field. In a diffusive two-dimensional (2D) electron gas, the spin orientation at a given…
