Superconductivity Appears in the Vicinity of an Insulating-Like Behavior in CeO${}_{1-x}$F${}_x$BiS${}_2$

Jie Xing, Sheng Li, Xiaxing Ding +2

Resistive and magnetization 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 cont…
