Ho4MgS7
Ho4MgS7 is a semiconducting ternary sulfide containing holmium, magnesium, and sulfur that is considered likely to be synthesizable.
About Ho4MgS7
Ho4MgS7 is a complex ternary sulfide incorporating holmium and magnesium. As a semiconducting material, it exhibits electronic properties that distinguish it from simple binary sulfides, making it a candidate for specialized solid-state applications.
Its status as a near-hull compound suggests that it is thermodynamically accessible for synthesis. The existence of multiple reported structures indicates that this material is a recognized entity in materials databases, warranting further investigation into its structural and electronic behavior.
Key Properties
Cross-validated computational properties for Ho4MgS7, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
