Ag2ScY
Ag2ScY is a semimetallic ternary intermetallic compound composed of silver, scandium, and yttrium that exists as a metastable phase.
About Ag2ScY
Ag2ScY is a complex ternary intermetallic compound composed of silver, scandium, and yttrium. Its electronic structure is characterized by a near-zero-gap profile, placing it in the category of semimetallic materials that exhibit unique conductive properties distinct from traditional insulators or simple metals. The material is categorized as being above the thermodynamic hull, suggesting it is a metastable phase that requires specific synthesis conditions to stabilize. With multiple reported structures across various databases, it remains a subject of interest for researchers investigating the phase space of silver-based ternary alloys.
Key Properties
Cross-validated computational properties for Ag2ScY, 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.
