Abstract: Antimony (Sb) substitution of less than 8% was examined on a single crystal of a layered superconductor NdO0.7F0.3BiS2. The superconducting transition temperature of the substituted samples decreased as Sb concentration increased. A lattice constant along the c-axis showed a large decrease compared with that along the a-axis. Since in-plane chemical pressure monotonically decreased as Sb concentration increased, the suppression of the superconductivity is attributed to the decrease in the in-plane chemical pressure.

Superconductivity appears in the vicinity of semiconducting-like behavior in CeO 1 − x F x BiS 2
TL;DR: In this paper, the parent phase of a bad metal was found to be bad metal instead of a band insulator and superconductivity appeared together with a semiconducting normal state, which is interpreted as approaching the Pomeranchuk transition with a von Hove singularity and the possible charge density-wave instability.
