Al2Co1Li1
Al2Co1Li1 is a semimetallic ternary compound composed of aluminum, cobalt, and lithium that is currently being investigated for its structural complexity and metastable nature.
About Al2Co1Li1
Al2Co1Li1 is a complex ternary compound composed of aluminum, cobalt, and lithium. Characterized as a near-zero-gap semimetallic material, it exhibits unique electronic properties that distinguish it from standard metallic alloys or insulating ceramics. Its structural landscape is notably diverse, with numerous reported configurations documented in materials databases.
As a material residing above the thermodynamic hull, Al2Co1Li1 is considered metastable, which presents significant interest for researchers investigating phase stability and synthesis pathways. Its role within the broader landscape of ternary intermetallics remains a subject of ongoing exploration, particularly regarding how its electronic character influences potential functional behavior in specialized environments.
Key Properties
Cross-validated computational properties for Al2Co1Li1, aggregated across 2 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.
