InOsSc2
InOsSc2 is a semiconducting ternary compound containing indium, osmium, and scandium that is currently studied for its structural complexity.
About InOsSc2
InOsSc2 is a complex ternary compound composed of indium, osmium, and scandium. As a semiconducting material, it represents a unique intersection of transition metal and post-transition metal chemistry, offering a distinct electronic profile for exploratory solid-state research.
Due to its position above the thermodynamic hull, this compound is considered metastable. Its existence across multiple reported structures highlights its role as a subject of interest for researchers investigating complex phase spaces and the synthesis of unconventional inorganic materials.
Key Properties
Cross-validated computational properties for InOsSc2, 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.
