spelling Experimental verification of PbBi2Te4 as a 3D topological insulatorKuroda, K.Ye, M.Eremeev, Sergey V.Koroteev, Yuri M.Krasovskii, E. E.Chulkov, Eugene V.Miyamoto, KojiShimada, K.Namatame, H.Taniguchi, M.Ueda, Y.Kimura, A.et al.The experimental evidence is presented of the topological insulator state in PbBi 2Te 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 observed two-dimensional isoenergy contours in the bulk energy gap are found to be the largest among the known three-dimensional topological insulators. This opens a pathway to achieving a sufficiently large spin current density in future spintronic devices. © 2012 American Physical Society.This work was financially supported by KAKENHI (Grants No. 20340092 and No. 23340105), Grant-in-Aid for Scientific Research (B) of JSPS.
