Pressure‐induced superconductivity. a) Pressure‐dependent isothermal resistance of ReS₂ at 5, 100, and 200 K. b) Magnetic field‐dependent resistance at 102 GPa. The upper critical field µ ₀ H _c2 is presented in the inset. The experimental data are fitted by the Ginzburg–Landau (GL) formula. c) Pressure–temperature (P–T) phase diagram of 2H‐MoS_2, demonstrating the respective regions of superconducting and metallic phases. d) Theoretical XRD spectra at 10 GPa together with experimental data at the indicated condition. e,f) Experimental XRD spectra showing clear splittings in the peaks of (011) and (113), demonstrating the occurrence of phase transitions. a,b) Reproduced with permission.^{[ 167 ]} Copyright 2017, Springer Nature. c) Reproduced with permission.^{[ 113 ]} Copyright 2018, American Physical Society. d–f) Reproduced with permission.^{[ 184 ]} Copyright 2016, American Physical Society.
