Connection topology of step edge state bands at the surface of a three dimensional topological insulator

Topological insulators (TIs) in the Bi _2 Se _3 family manifest helical Dirac surface states that span the topologically ordered bulk band gap. Recent scanning tunneling microscopy measurements have discovered additional states in the bulk band gap of Bi _2 Se _3 and Bi _2 Te _3 , localized at one-d...
