Effet Mössbauer de 119Sn dans les systèmes SnSBaS et SnSTl2S

Ternary Chalcogenides GeSb2Se3 and Ge3Sb4Se7 Containing a ∞1[Sb2Se2]2– 1D Chain and a 2D Structure Related to SnSe

“…The search for layered compounds with a structure type similar to that of black phosphorus or SnSe may provide a new structure–property correlation for applications. ,,, To date, chalcogenides with structures related to black phosphorus were found in binary metal chalcogenides MX containing the group 14 element MX (M = Ge, Sn; X = S, Se). Ternary chalcogenides with structures similar to SnSe include Ba x Sn 1– x S ( x ≤ 0.5), − solid solutions of the group 14 element chalcogenides, , and doped MSe (M = Ge, Sn) compounds, ,− and the mineral Pääkkönenite Sb 2 AsS 2 is an example reported with As–As contacts . Other than the doped metal chalcogenides on metal or chalcogen sites, ternary crystalline chalcogenide in a Ge–Sb–Se system is unknown.…”
