HgInSc2 is a semimetallic ternary compound composed of mercury, indium, and scandium that is considered a viable candidate for experimental synthesis.
About HgInSc2
HgInSc2 is a complex ternary inorganic compound composed of mercury, indium, and scandium. Its electronic character identifies it as a near-zero-gap material, positioning it within the semimetallic regime where conduction properties are highly sensitive to structural variations.
Given its thermodynamic stability near the hull, this material is considered a promising candidate for experimental synthesis. The existence of multiple reported structures across databases highlights its significance as a subject of ongoing investigation in solid-state chemistry.
Key Properties
Cross-validated computational properties for HgInSc2, 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.
