Fig. 4: Elemental distributions of the predicted stable AMM′Q3 compounds.

Distributions of the cations (A, M, M′) forming the 628 predicted stable AMM′Q3 compounds in the three categories: Type-I, Type-II, and Type-III. The bar corresponding to an element represents the number of stable compounds containing it. Total number of sulfides, selenides, and tellurides are mentioned in each panel. These compounds exclude the experimentally known 192 AMM′Q3 compounds.
