Title: Superconductivity in the 2-Dimensional Homologous Series AM_mBi₃Q_5+m (m =1, 2) (A=Rb, Cs; M=Pb, Sn; Q=Se, Te)

Abstract

Here, superconductivity in the two-dimensional AM_mBi₃Q_5+m family of semimetals is reported. The AMBi₃Te₆ (m=1) and AM₂Bi₃Te₇ (m=2) members of the homologous series with A=Rb, Cs and M=Pb, Sn undergo a bulk superconducting transition ranging from 2.7 to 1.4 K depending on the composition. The estimated superconducting volume fraction is about 90 %. Superconducting phase diagrams as a function of chemical pressure are constructed for the solid solution products of each member of the homologous series, AMBi_3-xSb_xTe_6-ySe_y and AM₂Bi_3-xSb_xTe_7-ySe_y (0≤x≤3 or 0≤y≤2). The structural flexibility of the ternary AM_mM'₃Te_5+m semiconducting homology to form isostructural analogues with a variety of metals, M=Pb, Sn; M'=Bi, Sb, gives access to a large number of electronic configurations and superconductivity due to chemical pressure effects.

The new chloro-sulfosalt Pb{sub 3+x}Sb{sub 3-x}S{sub 7-x}Cl{sub 1+x} (x{approx}0.45) has been synthesized at 500 deg. C from a mixture of PbS, PbCl{sub 2} and Sb{sub 2}S{sub 3}. It crystallizes in the orthorhombic system (space group Pbam), with a=15.194(3) A, b=23.035(5) A, c=4.0591(8) A, V=1420.6 A{sup 3}, Z=4. The crystal structure has been solved by X-ray single-crystal study, with a final R=0.0497.

Superconductivity in the Narrow Gap Semiconductor RbBi_11/3Te₆

Journal Article Malliakas, Christos D. ; Chung, Duck Young ; Claus, Helmut ; ... - Journal of the American Chemical Society

Superconductivity was discovered in the layered compound RbBi_11/3Te₆, featuring Bi vacancies and a narrow band gap of 0.25(2) eV at room temperature. In addition, a sharp superconducting transition at similar to 3.2 K was observed in polycrystalline ingots. The superconducting volume fraction of oriented single crystals is almost 100%, confirming bulk superconductivity. Systematic Se and Sb substitutions in RbBi_11/3-ySb_ySe_xTe_6-x, revealed a dependence of the superconducting transition on composition that can increase the T_c up to similar to 10%. The RbBi_11/3Te₆ system is the first member of the new homologous series Rb[Bi_2n+11/3Te_3n+6] with infinite Bi₂Te₃-like layers. Lastly, the large degree ofmore »« less

For compounds of the type M{sub 2}X{sub 3} (Bi{sub 2}Te{sub 3}, Bi{sub 2}Se{sub 3}, Sb{sub 2}Te{sub 3}), doping with Ge (Sn or Pb), as well as addition of excess cations, leads to the formation of continuous series of 1 D superstructures which can now be characterized by means of electron microscopy, The systems Ge{sub {delta}}Bi{sub 2}Te{sub 3} and Bi{sub 2+{delta}}Se{sub 3} are discussed as model systems, Analysis of the electron diffraction patterns with the fractional shift method suggests the superstructures are built up of sequences of five- and seven-layer lamellae.

Journal Article Bos, J W. G. ; Cava, R J ; Zandbergen, H W ; ... - Physical Review. B, Condensed Matter and Materials Physics

The structures and thermoelectric properties of the (Bi{sub 2}){sub m}(Bi{sub 2}Te{sub 3}){sub n} homologous series, derived from stacking hexagonal Bi{sub 2} and Bi{sub 2}Te{sub 3} blocks, are reported. The end members of this series are metallic Bi and semiconducting Bi{sub 2}Te{sub 3}; nine members of the series have been studied. The structures form an infinitely adaptive series and a unified structural description based on a modulated structure approach is presented.

Pb{sub 5}Bi{sub 24}Se{sub 41}: A new member of the homologous series forming topological insulator heterostructures

Journal Article Segawa, Kouji ; Taskin, A. A. ; Ando, Yoichi - Journal of Solid State Chemistry

We have synthesized Pb{sub 5}Bi{sub 24}Se{sub 41}, which is a new member of the (PbSe){sub 5}(Bi{sub 2}Se{sub 3}){sub 3m} homologous series with m=4. This series of compounds consist of alternating layers of the topological insulator Bi{sub 2}Se{sub 3} and the ordinary insulator PbSe. Such a naturally-formed heterostructure has recently been elucidated to give rise to peculiar quasi-two-dimensional topological states throughout the bulk, and the discovery of Pb{sub 5}Bi{sub 24}Se{sub 41} expands the tunability of the topological states in this interesting homologous series.
