Discovery of a New Phase in Thin Flakes of KV₃Sb₅ under Pressure.

ABSTRACT: Results of magnetotransport measurements are reported on KV₃Sb₅ thin flakes under pressure. The zero-field electrical resistance reveals an additional anomaly emerging under pressure (p), marking a previously unidentified phase boundary T*(p). Together with the established T_CDW(p) and T_c(p), denoting the charge-density-wave transition and a superconducting transition, respectively, the temperature-pressure phase diagram of KV₃Sb₅ features a rich interplay among multiple phases. The Hall coefficient evolves reasonably smoothly when crossing the T* phase boundary compared with the variation when crossing T_CDW, indicating the preservation of the pristine electronic structure. The mobility spectrum analysis provides f
