Evidences of inner Se ordering in topological insulator PbBi(2)Te(4)-PbBi(2)Se(4)-PbSb(2)Se(4) solid solutions

In topological insulators (TIs), carriers originating from non-stoichiometric defects hamper bulk insulation. In (Bi,Sb)(2)(Te,Se)(3) TIs (BSTS TIs), however, Se atoms strongly prefer specific atomic sites in the crystal structure (Se ordering), and this ordering structure suppresses the formation o...
