...Soon after the theoretical prediction of the 3D topological insulator in the Bi2Te3, Sb2Te3 (Zhanget al., 2009) and Bi2Se3 (Xia et al., 2009; Zhanget al., 2009) class of materials, angle-resolved photoemission spectroscopy (ARPES) observed the surface states with a single Dirac cone (Chenet al.,…...

...Simpler versions of the 3D topological insulator were theoretically predicted in Bi2Te3, Sb2Te3 (Zhanget al., 2009) and Bi2Se3 (Xia et al., 2009; Zhanget al., 2009) compounds with a large bulk gap and a gapless surface state consisting of a single Dirac cone....
