Al2IrTc
Al2IrTc is a semiconducting ternary alloy containing aluminum, iridium, and technetium that is primarily studied for its structural properties in catalytic research.
About Al2IrTc
Al2IrTc is a complex intermetallic compound belonging to the platinum-group alloy catalyst class. Characterized by its semiconducting electronic nature, this material represents an intriguing intersection of transition metal chemistry and structural complexity. Its presence across multiple databases highlights its significance in the study of ternary alloy systems.
Despite its thermodynamic position above the hull, which suggests potential instability under standard conditions, the existence of multiple reported structures makes it a subject of interest for computational materials science. It serves as a model for understanding how iridium and technetium can be integrated into aluminum-rich frameworks to tune electronic properties for catalytic research.
Key Properties
Cross-validated computational properties for Al2IrTc, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse family of platinum-group alloys, Al2IrTc occupies a unique niche compared to more stable, well-characterized members like As2Ir or IrSe2. While many of its siblings are studied for their robust metallic behavior or specific superconducting properties, Al2IrTc is notable for its semiconducting character, which distinguishes it from the predominantly metallic nature of compounds like BaPd or LaRh.
