From: Visualization of spin-polarized surface resonances in Pb-based ternary topological insulators
Spin-resolved band structures for x = 0.55, 0.70, 0.79. (a, b) SARPES images recorded with the p-polarized light along \(\bar{\Gamma}\bar{\rm{M}}\) for x = 0.55, 0.70, respectively. The color scale displays both spin polarization and photoemission intensity. (c) An enlarged SARPES image and (d) the MDCs for x = 0.55 at 20, 40, 60 meV. Each MDC is obtained by summing the photoemission intensity within an energy window of 20 meV. Symbols in (d) represent the peak positions of MDCs for the guide to the eye. (e) A SARPES image for x = 0. 79 along \(\bar{\Gamma}\bar{\rm{M}}\). (f) EDCs obtained from (e) at the photoelectron emission angles of \(\theta_{e}\) . Symbols represent the peak positions. (g) Schematic drawing of the band structure of the TSS and the spin-polarized surface resonances.
