From: Evidences of inner Se ordering in topological insulator PbBi2Te4-PbBi2Se4-PbSb2Se4 solid solutions
(a) The simulated pXRD patterns of 3 different Se geometries and the experimental pXRD data of PbBi2(Te1-ySey)4 (y = 0.5); (b) pXRD simulation patterns with different Se ordering degree are presented with experimental data of PbBi2(Te1-ySey)4 (y = 0.5); (c) pXRD simulation patterns of different Se ordering in Pb(Bi1-xSbx)2(Te1-ySey)4 (x = 0.8, y = 0.5) are presented with experimental data.
