About HoLiS2
HoLiS2 is a ternary sulfide compound composed of holmium, lithium, and sulfur. As a thermodynamically stable material residing on the convex hull, it represents a robust phase within its chemical system, offering a reliable foundation for materials research. The electronic character of this compound is classified as semiconducting, which suggests potential utility in optoelectronic or sensing technologies where tunable charge transport is required. Its structural diversity, evidenced by multiple reported configurations across various databases, highlights its complexity and the interest it garners in solid-state chemistry. This material serves as an important subject for understanding how rare-earth elements interact with alkali metals and chalcogens to form stable, functional lattices.
Key Properties
Cross-validated computational properties for HoLiS2, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
