The Rashba effect is fundamental to the physics of two-dimensional electron systems and underlies a variety of spintronic phenomena. It has been proposed that the formation of Rashba-type spin splittings originates microscopically from the existence of orbital angular momentum (OAM) in the Bloch wave functions. Here, we present detailed experimental evidence for this OAM-based origin of the Rashba effect by angle-resolved photoemission (ARPES) and two-photon photoemission experiments for a…

Hierarchical spin-orbital polarization of a giant Rashba system

Angle-resolved photoemission reveals the emergence of complex orbital texture concomitant with spin splitting in the Rashba compound BiTeI, and necessitates a reinterpretation ofspin splitting in Rashba-like systems and opens new possibilities for controlling spin polarization through the orbital sector.

Orbital-angular-momentum based origin of Rashba-type surface band splitting.

The existence of local orbital angular momentum on the surfaces of high-Z materials plays a crucial role in the formation of Rashba-type surface band splitting and the band splitting originates from electric dipole interaction, not from the relativistic Zeeman splitting as proposed in the original Rashba picture.
