IrLiSi2
IrLiSi2 is a semiconducting ternary alloy containing iridium, lithium, and silicon that is currently being investigated for its structural characteristics.
About IrLiSi2
IrLiSi2 is a complex ternary compound categorized within the platinum-group alloy catalysts. Characterized by its semiconducting electronic nature, this material represents a unique intersection of transition metal, alkali metal, and metalloid chemistry.
While it is currently identified as being above the thermodynamic hull, suggesting potential instability under standard conditions, it remains a subject of interest in structural databases. Its existence across multiple reported structures highlights the ongoing exploration of iridium-based ternary systems in materials science.
Key Properties
Cross-validated computational properties for IrLiSi2, 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.
