“…The combination of the elemental bismuth or antimony bilayers and quintuple blocks of Bi 2 Te 3 (orSb 2 Te 3 and Bi 2 Se 3 ) and the septuple blocksof the GeBi 2 Te 4 , PbBi 2 Te 4 ternaries are also found to be stable structures [6]. Taking into account alternation Here we present the synthesis and elucidation of a crystal structure of 9P-type heterostructured new ternary compound -SnBi 4 Te 4 , which is consists of alternating bismuth bilayers and SnBi 2 Te 4 septuple packets.…”

“…Recently preparation of mixed-layered compounds having thermoelectric properties are considered to be a more effective method for material design [6][7]. The literature data shows that, the systems -( = Ge, Sn, Pb; =Sb, Bi; =Se, Te) host tetradymite-type layered ternary compounds and exhibit promising thermoelectric properties [7][8][9][10][11][12][13][14].…”

Considering structural features of the already known tetradymite-like layered chalcogenide phases, we have attempt to synthesize a new mix-layered compound, SnBi 4 Te 4 . The newly synthesized alloy examined by means of differential thermal analysis, powder X-ray diffraction and scanning electron microscope techniques.The melting nature of the discovered phase is found to be incongruently at 831 K. The crystal structure of the SnBi 4 Te 4 was elucidated from powder pattern by Rietveld method. The determined crystal structure was found to derived from tetradymite type and featured by the alternation of theseven-layered (septuple) blocks of SnBi 2 Te 4 and bismuth bilayers. The result of this work, the existence of a new -SnBi 4 Te 4 compound in the Sn-Bi-Te ternary systemcan shed light for the incoming research works to search for similar phases in the other releated A IV -Bi-Te ( = , , ) systems.

“…properties and are considered a promising material for solar-powered devices [4][5][6][7][8][9][10][11][12]. In recent years, the topological insulator properties and 3D Rashba spin splitting have been observed in these compounds [13][14][15][16][17], that made these alloys even more attractive.…”

Based on the results of the DTA and X-ray phase analysis, the phase equilibria in the BiTeI-BiSI system were studied and the T-x phase diagram was constructed. It was established that the system is stable in the subsolidus area and there are ~7-8 mol % and ~5 mol% solid solution areas based on BiTeI and BiSI compounds at room temperature, accordingly. In2016 general, the system is nonquasibinary. Bi 19 S 27 I 3 (0-33 mol % BiTeI) and tetradymite-Bi 2 Te 2 S (33-83mol% BiTeI) phases primarily crystallize from the liquid phase in the wide composition ranges.

“…[12][13][14][15][16][17] Search and development of methods for the directed synthesis of new multicomponent phases and materials requires the study of phase equilibria in the relevant systems. 18,19 For this case, the systems including compounds which are structural or formula analogs are the greatest interest since the formation of broad areas of substitutional solid solutions can be expected in them. [20][21][22][23][24] Herein, the phase equilibria in the MnGa 2 Tе 4 -Mn-In 2 Tе 4 system are studied, the crystal structures of the MnGaInTe 4 and MnIn 2 Te 4 are refined, as well as the EPR and Raman spectra for the MnGaInTe 4 crystals are measured, and the temperature dependences of the electrical conductivity and the Hall Effect of the MnGaInTe 4 are investigated.…”

The phase equilibria in the MnGa 2 Tе 4 -MnIn 2 Tе 4 system were experimentally investigated by means of differential thermal analysis and powder X-ray diffraction technique. It was found that this system is quasi-binary and characterized by dystectic and eutectic equilibria and the formation of a wide area of solid solutions based on the starting compounds. The crystal structures of the MnGaInTe 4 and MnIn 2 Tе 4 were refined by the Rietveld method using powder X-ray diffraction data. It was established, that both phases crystallize in the tetragonal system (Space group I-42m). Electron paramagnetic resonance and Raman spectra, as well as the temperature dependences of the electrical conductivity and the Hall effect for the MnGaInTe 4 crystal, were studied.
