Extended Data Fig. 9: Spin-resolved ARPES results of the topological surface state of Bi2Se3.
a, ARPES intensity plot showing band dispersions across \(\bar{\Gamma }\). b, Spin-resolved MDCs at an energy indicated by black dashed line in a. Red and blue curves are spin-up and spin-down signals. c, Momentum-dependent spin polarizations calculated by the asymmetry of the spin-up and spin-down signals in b. Red and blue filled areas highlight the spin-up and spin-down polarizations.
