Namatame, M. Taniguchi, Y. Ueda, and A. Kimura The experimental evidence is presented of the topological insulator state in PbBi 2 Te 4 . A single surface Dirac cone is observed by angle-resolved photoemission spectroscopy with synchrotron radiation. Topological invariants Z 2 are calculated from the ab initio band structure to be 1;(111). The observ... [Phys. Rev. Lett. 108, 206803] Published Tue May 15, 2012
