Bonding-unsaturation-dependent superconductivity in P-rich sulfides
Fig. 1. (a) Convex hull constructed with thermodynamically stable P–S compounds at 50 and 100 GPa. For clarity, we have offset the formation enthalpy by −0.1 eV for 100 GPa. The full convex hull is shown in Fig. S1. (b) Pressure–composition phase diagram of stable P–S compounds.
