Nonlinear Rashba spin splitting in transition metal dichalcogenide monolayers.
Single-layer transition-metal dichalcogenides (TMDs) such as MoS2 and MoSe2 exhibit unique electronic band structures ideal for hosting many exotic spin-orbital orderings. It has been widely accepted that Rashba spin splitting (RSS) is linearly proportional to the external field in heterostructure interfaces or to the potential gradient in polar materials. Surprisingly, an extraordinary nonline...
متن کاملRashba-type spin splitting and spin interference of the Cu(111) surface state at room temperature
We report on the measurement of the Rashba-type spin splitting of the Shockley surface state on Cu(111) by spinand angle-resolved photoemission at room temperature. Along the spatial direction expected for a Rashba-type effect the measured spin splitting corresponds to what has previously been reported by first principle calculations which were verified by high resolution ARPES using low temper...
متن کاملIdeal two-dimensional electron systems with a giant Rashba-type spin splitting in real materials: surfaces of bismuth tellurohalides.
Spintronics is aimed at actively controlling and manipulating the spin degrees of freedom in semiconductor devices. A promising way to achieve this goal is to make use of the tunable Rashba effect that relies on the spin-orbit interaction in a two-dimensional electron system immersed in an inversion-asymmetric environment. The spin-orbit-induced spin splitting of the two-dimensional electron st...
متن کاملStructural influence on the Rashba-type spin splitting in surface alloys
The Bi/Ag(111), Pb/Ag(111), and Sb/Ag(111) surface alloys exhibit a two-dimensional band structure with a strongly enhanced Rashba-type spin splitting, which is in part attributed to the structural asymmetry resulting from an outward relaxation of the alloy atoms. In order to gain further insight into the spin splitting mechanism, we have experimentally determined the outward relaxation of the ...
متن کامل2 00 4 Rashba spin splitting in quantum wires
This article presents an overview of results pertaining to electronic structure, transport properties, and interaction effects in ballistic quantum wires with Rashba spin splitting. Limits of weak and strong spin–orbit coupling are distinguished, and spin properties of the electronic states elucidated. The case of strong Rashba spin splitting where the spin–precession length is comparable to th...
