In 2012, we discovered superconductivity in Bi4O4S3 and LaO1− x F x BiS2, whose crystal
structures are composed of alternate stacks of a BiS2-type conduction layer and a blocking …

Interlayer coupling and stacking order play essential roles in shaping the exotic electronic
properties of two-dimensional materials. Here, we employ restacked TaS2─ a novel …

BiS2-based layered superconductors have attracted considerable interest owing to the
relatively large spin–orbit coupling of bismuth 6 p orbitals, the strong coupling nature by …

Very recently a new family of layered materials, containing BiS 2 planes, was discovered to
be superconducting at temperatures up to T c= 10 K, raising questions about the mechanism …

Through a combination of x-ray diffraction, electrical transport, magnetic susceptibility, and
heat-capacity measurements, we report the effect of La doping on Sr in the newly discovered …

We discuss the electronic structure, lattice dynamics, and electron-phonon interaction of the
newly discovered superconductor LaO 0.5 F 0.5 BiS 2 using density-functional-based …

With the addition of oxygen into the chain-like bismuth sulfide of Bi2S3, there are two
interesting functional compounds of Bi2O2S (photoelectric) and Bi4O4S3 (superconducting) …

We report a strategy to induce superconductivity in the BiS 2-based compound LaOBiS 2.
Instead of substituting F for O, we increase the charge-carrier density (electron dope) via …

Superconductivity (SC) and charge-density wave (CDW) are two contrasting yet relevant
collective electronic states, which have received sustained interest for decades. Here, we …

Abstract BiCh2-based compounds (Ch: S, Se) are a new series of layered superconductors
and the mechanisms for the emergence of superconductivity in these materials have not yet …
