Figure 5: The unconventional spin-layer locking by R-2 effect proposed for monolayer PtSe2.

From: Direct observation of spin-layer locking by local Rashba effect in monolayer semiconducting PtSe2 film

Figure 5

(a) Spin texture of the two Se layers from first-principles calculation for the four bands, respectively. The arrow colours represent the spin helicities: the blue arrows are counterclockwise and the red arrows are clockwise. The arrow size indicates the strength of spin polarization. (b) The diagram of Se p orbitals and Pt d orbitals, which dominate the spin texture of bands near Fermi level. (c) The schematic diagram for the new spin-locking mechanism of monolayer PtSe2 thin film on Pt(111).
