GeHgSr2
GeHgSr2 is a semimetallic ternary intermetallic compound that is considered a promising candidate for experimental synthesis.
About GeHgSr2
GeHgSr2 is a complex ternary intermetallic compound composed of germanium, mercury, and strontium. Its electronic character is defined as near-zero-gap, placing it in the category of semimetallic materials that exhibit intriguing conductive properties near the Fermi level.
As a near-hull material, it is considered a strong candidate for experimental synthesis. The presence of multiple reported structures across various databases highlights its significance as a subject of ongoing computational and structural investigation in solid-state chemistry.
Key Properties
Cross-validated computational properties for GeHgSr2, 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.
