Structural 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 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 کاملLarge Rashba spin splitting of a metallic surface-state band on a semiconductor surface
The generation of spin-polarized electrons at room temperature is an essential step in developing semiconductor spintronic applications. To this end, we studied the electronic states of a Ge(111) surface, covered with a lead monolayer at a fractional coverage of 4 / 3, by angleresolved photoelectron spectroscopy (ARPES), spin-resolved ARPES and fi rst-principles electronic structure calculation...

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...
