Fig. 1: Pressure-induced superconductivity in 1T-TaS2.
From: Structural phase transition and superconductivity hierarchy in 1T-TaS2 under pressure up to 100 GPa
Temperature-dependent resistivity under pressures ranging from a 17.5 to 40.9 GPa (normalized to the same magnitude at elevated pressures) and b 40.9 to 98.8 GPa in run 1. c Temperature-dependent resistance curves under high pressure in run 2. Zero resistance has been measured since 50.8 GPa. d shows the R–T curve under increasing magnetic field at 97.1 GPa. The criterion for determining Tc in two runs is shown in c. Inset of d plots the best fit of Tc vs H using the empirical formula Hc2(T) = Hc2*(1 – T/Tc)1 + α. e Temperature–pressure phase diagram of TaS2; the black solid squares and triangles represent the TCDW and Tc from previous electrical resistivity measurements20. The red solid circles and green stars represent the Tc measured in this study.
