Hexagonal supertetrahedral gallium: a cluster-based three-dimensional topological metal

Two novel three-dimensional allotropes, designated as hexagonal supertetrahedral aluminum and gallium (h-Al/h-Ga), are proposed based on a hexagonal diamond structure and share the same space group symmetry (P63/mmc) as hexagonal diamond. First-principles calculations demonstrate their structural st...
