| description | Layered La(O,F)BiS<sub>2</sub> exhibits drastic enhancements of the superconducting transition temperature (<i>T</i><sub>c</sub>) under high pressure among the BiS<sub>2</sub>-based superconducting family. However, the high-pressure application beyond a high-<i>T</i><sub>c</sub> phase of the monoclinic structure has not been conducted. In this study, the electrical transport properties in La(O,F)BiS<sub>2</sub> single crystal are measured under high pressures up to 83 GPa. An insulating phase without superconductivity is observed under a higher-pressure region above 16 GPa. Moreover, the sample exhibits metallicity and superconductivity above 60 GPa. The newly observed hidden semiconducting phase and reentrant superconductivity have attracted much attention in BiS<sub>2</sub>-based compounds. |
