Fig. 4.
Pressure dependence of Tc values for typical superconductors. The green filled circles represent the Tc values of well-known superconductors from experiments (1–10, 16–18, 25, 31–33). The blue half-filled (unfilled) rhombuses represent the Tc values of the predicted thermodynamically stable (metastable) hydrides (14, 15, 19, 20, 24, 29, 30, 48). The red half-filled (unfilled) stars mark the Tc values (with μ* of 0.1) of the thermodynamically stable (metastable) LaSc2H24 by considering anharmonic effects at a pressure range of 150 to 300 GPa.
