“…In accordance with results of EDX (energy dispersive X-ray spectroscopy) mapping, which was earlier reported earlier in Ref. [28], Bi, Te, Sm and Se are uniformly distributed within the particles, and, in accordance with results of SAED (selected area electron diffraction) experiment, the individual Bi 1.95 Sm 0.05-Te 2.7 Se 0.3 particles in the starting powder are single-crystalline particles with crystal Bi 2 Te 3 structure.…”
