Fig. 1: Convex hulls for selected lanthanum ternary hydrides at 300 GPa.
From: First-principles search of hot superconductivity in La-X-H ternary hydrides
The convex hull shown are for La–N–H (a) and La–B-H (b), and La–Ga-H (c). Blue circles and red squares represent stable and metastable phases, respectively.
