WebApr 12, 2024 · We constructed a series of ternary AXH 6 hydrides using A15 GaH 3 as the parent structure for atomic substitution. In A15 GaH 3 (Figure 1 a), two Ga atoms form a body-centered cubic (bcc) lattice, and six H atoms occupy half of the tetrahedral interstices of the Ga lattice. If two Ga atoms in GaH 3 are replaced by two different X and A atoms, …
