InRh2Ta
InRh2Ta is a semiconducting ternary intermetallic compound composed of indium, rhodium, and tantalum that serves as a subject for catalytic materials research.
About InRh2Ta
InRh2Ta is a complex ternary intermetallic compound classified within the platinum-group alloy catalysts. Characterized by its semiconducting electronic nature, this material represents a specialized structural arrangement of indium, rhodium, and tantalum atoms. Its existence is documented across multiple structural databases, highlighting its interest in fundamental materials research.
Because it resides above the thermodynamic hull, InRh2Ta is considered a metastable phase. Its unique composition makes it a subject of study for researchers seeking to understand how transition metal alloys can be tuned for catalytic applications despite their inherent energetic instability compared to more common ground-state phases.
Key Properties
Cross-validated computational properties for InRh2Ta, 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.
