“…For MnSb4Te7, all diffraction patterns are indexed in the trigonal structure with lattice parameters a = 4.2413 Å and c = 23.761 Å. We note that determined unit cell parameters of MnSb2Te4 are in good agreement with already reported ones elsewhere in [27,28]. However, the narrow homogeneity field of the MnSb2Te4 compound may cause some deviation from the values of the a and c parameters which suggests that other results can also be acceptable.…”

By using Differential Thermal Analysis (DTA) and Powder X-ray Diffraction (PXRD) techniques, the phase diagram of the MnTe-Sb2Te3 system has been constructed for the first time in the entire composition range. The system features two ternary layered van der Waals (vdW) compounds. Apart from known MnSb2Te4, novel MnSb4Te7 which a structural analogous of the known MnBi4Te7 was found in the system. Crystal structure parameters of both compounds were determined by Rietveld refinement using the fundamental parameter approach. Both compounds were found to decompose via peritectic reactions and possess significant homogeneity ranges. The title system is also characterized by the existence of the wide solid solution field based on the starting Sb2Te3. The present results would be useful for the bulk single crystal growth of both compounds from the liquid phase via the determination of primary crystallization areas.

“…As the information on topological insulators increased [8,9], layered bismuth and antimony chalcogenides were also proven to host topological surface states [10][11][12]. Ongoing research in this field revealed that tetradymitelike ternary compounds formed in A IV -B V -Te systems (A IV -Ge, Sn, Pb; B V -Sb, Bi) systems including A IV B V 2 Te 4 , A IV B V 4 Te 7 , A IV B V 6 Te 10 are also three-dimensional topological insulators [13][14][15][16][17][18][19][20][21]. The creation of new multicomponent functional materials is possible based on the phase equilibria data of the corresponding systems.…”

Using the analytical option of the Origin Lab computer program, the analytical dependences of the liquidus temperature on the composition for the PbTe-Bi2Te3, PbTe-Sb2Te3, Bi2Te3-Sb2Te3 boundary systems of the PbTe-Bi2Te3-Sb2Te3 ternary system were determined. Based on these dependencies and thermal analysis data of the ternary system, the analytical model of the temperature-composite dependence of the crystallization surfaces of PbTe, Sb2Te3, Bi2Te3 compounds and PbBi2Te4, PbBi4Te7, PbBi6Te10 phases in the PbTe-Bi2Te3-Sb2Te3 system was determined. The resulting equations made it possible to visualize the phase diagram of the PbTe-Bi2Te3-Sb2Te3 system from the side of the PbTe-Bi2Te3 in 3D coordinates. The analytical model of the phase diagram of the PbTe-Bi2Te3-Sb2Te3 system allowed constructing a threedimensional image of equilibrium phases from different angles, to obtain two-dimensional projections and to tabulate the coordinates of the phase diagram.

“…Data analysis indicates that in A IV -B V -Te systems, besides above mentioned homologous series, there can also exist phases relevant to mBi2 -𝐴 𝐼𝑉 𝐵 2 𝑉 Te4 homologous series. The first two members of this series have been reported in recent years: SnBi4Te4 [34] and GeSb4Te4 [35]. Identification of these compounds increases the probability of such phases in a similar Ge -Bi -Te system.…”

Taking as a base structural properties of the tetradymite-like layered chalcogenide compounds, a novel ternary GeBi4Te4 phase was predicted and synthesized. The polycrystal of this compound was synthesized and its single-crystal was grown by the vertical Brigman-Stokbarger method. The phase composition of obtained samples was analyzed by differential thermal analysis (DTA), X-ray powder diffraction (XRD), and scanning electron microscope (SEM). It was determined that the novel phase melts peritectially at 538 °C and has the following lattice parameter values in a hexagonal configuration: a=4,4071(6)Å, c=17,384(2)Å (sp. gr P3m1). This crystal structure is considered a derivative of tetradymite-like layered chalcogenides and consists of alternating Bi bilayers and GeBi2Te4 septuple packets.
