## Description

- description: 'The formation of the topological surface state originates from bulk
    band inversion at the top of the valence band and the bottom of the conduction
    band. The transition between normal and topological insulators is known as a topological
    phase transition. Here we show spin-polarized electronic states of Pb-based ternary
    topological insulators Pb(Bi1-xSbx)2Te4 (x = 0.55, 0.70, 0.79) investigated by
    spin- and angle-resolved photoemission spectroscopy and first-principles calculations.
    We visualize a pair of spin-polarized surface resonances dispersing along the
    upper edge of projected bulk bands in occupied states. Interestingly, a branch
    of the spin-polarized surface resonances continuously connects to the topological
    surface state. The coexistence of the topological surface state and the spin-polarized
    surface resonances can be explained by considering the topological phase transition. '
