Extended Data Fig. 7: Polarization-dependent ARPES data.
a-c, ARPES intensity plots along Γ−X, Y−M and Γ−M measured at 20 K with hv = 67 eV under LV polarization. d-f, Same as a-c but measured with LH polarization. Red, blue, and green dashed curves are spin-up, spin-down, and spin-degenerate bands at kz = 0.
