Lacking inversion symmetry
WebDec 14, 2024 · Therefore, a nonzero spin signal is expected, despite inversion symmetry and the lack of resolved band splitting. This spin texture stems from differences in photoemission matrix elements for different components of the wave function, as well as the surface sensitivity of the measurement and interference effects.
