Figure 3. Spin texture measured along the K-Γ-K direction and the overall spin texture.
(a) ARPES data measured at different emission angles. (b,c) Spin-resolved energy distribution curves (EDCs) for the in-plane tangential direction at emission angles of 8° and −8°, respectively. The error bars indicate the statistical fluctuation in determining the spin polarizations (proportional to where N is the photoemission intensity). (d) Spin-resolved EDCs for the in-plane tangential direction at emission angle of 22°. (e) Spin-resolved EDCs along the out-of-plane direction at emission angle of 8°. (f,g) Spin-resolved EDCs for the radial direction at emission angles of 8° and −8°, respectively. (h) Overview of the spin texture of monolayer PtSe2 from spin-ARPES measurements.
