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 …

Oxysulfides, as one type of important mixed-anion inorganic functional systems, possess the
coexistence of two different anions (O 2− and S 2−) in their crystal structures and could be …

Resistive and magnetic properties have been measured in BiS 2-based samples CeO 1− x F
x BiS 2 with a systematic substitution of O with F (0< x< 0.6). In contrast to the band-structure …

We report synthesis and superconductivity at 3.7 K in PrO 0.5 F 0.5 BiS 2. The newly
discovered material belongs to the layered sulfide based RE O 0.5 F 0.5 BiS 2 compounds …

The progress of unconventional superconductors at the two-dimensional (2D) limit has
inspired much interest. Recently, a new superconducting system was discovered in the …

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 …

Abstract Novel BiS 2-based superconductors LaO 1− x F x BiS 2 prepared by a high-
pressure synthesis technique were systematically studied. It was found that the high …

Phase pure samples of LaOBiS2 and LaO0. 5F0. 5BiS2 are synthesized by conventional
solid state reaction route via vacuum encapsulation technique at 800° C for 12h. Both the …
