ScClO
ScClO is a metastable, insulating oxyhalide of scandium that is primarily studied for its electronic properties and structural characteristics.
About ScClO
ScClO is an insulating compound characterized by a wide electronic band gap. As a metastable material, it represents a specialized structural configuration within its chemical system, offering researchers a distinct platform for studying phase stability and electronic behavior in complex oxyhalides.
Its significance lies in its potential for specialized electronic applications where wide-gap insulators are required. The material is currently a subject of interest in computational and experimental studies aimed at understanding the structural diversity of scandium-based compounds.
Key Properties
Cross-validated computational properties for ScClO, 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.

Reported Structures
Lowest-energy structures reported for ScClO, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom.
