Sc2
Sc2 is a thermodynamically stable metallic dimer composed entirely of scandium atoms.
About Sc2
Sc2 is a metallic scandium dimer that exists as a thermodynamically stable phase on the convex hull. Its electronic character is defined by its metallic nature, lacking a band gap, which makes it a subject of significant interest in fundamental condensed matter studies.
With hundreds of reported structures across major databases, this compound serves as a key reference point for understanding scandium-based bonding and cluster behavior. Its stability and structural diversity provide essential data for computational modeling and experimental validation in inorganic chemistry.
Key Properties
Cross-validated computational properties for Sc2, aggregated across 4 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.
