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 …

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 …

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 …

In 2012, a new layered superconductor where BiS 2 layer is the superconducting layer was
discovered. So far, seven types of BiS 2-based superconductors and two related …

Atomically thin oxychalcogenides have been attracting intensive attention for their
fascinating fundamental properties and application prospects. Bi2O2Se, a representative of …

We have synthesized a novel europium bismuth sulfofluoride, Eu3Bi2S4F4, by solid-state
reactions in sealed evacuated quartz ampules. The compound crystallizes in a tetragonal …

A novel family of superconductors based on BiS 2-based superconducting layers were
discovered in 2012. In short order, other BiS 2-based superconductors with the same or …

Sb-substituted CeOBiS 2 single crystals with 0.2–1.0 mm size have been successfully grown
using CsCl/KCl flux. Sb substitution strongly suppressed the superconductivity in CeOBiS 2 …

Single crystals of La (O, F) BiSSe were grown by using a CsCl flux method. Single crystal X-
ray structural analysis reveals that the crystal structure is isostructural to the BiS 2-or BiSe 2 …

The pressure effect on the newly discovered charge-transferred BiS 2-based
superconductor, Eu 3 Bi 2 S 4 F 4, with a T c of 1.5 K at ambient pressure, is investigated by …
