About P2S8Sc2
P2S8Sc2 is a complex ternary chalcogenide composed of phosphorus, sulfur, and scandium. It exhibits semiconducting electronic properties and is recognized for its thermodynamic stability, as it sits on the convex hull of its constituent elements.
This material is of significant interest in solid-state chemistry due to its structural diversity, with multiple reported configurations across crystallographic databases. Its specific arrangement of atoms suggests potential for specialized electronic or optoelectronic applications.
Key Properties
Cross-validated computational properties for P2S8Sc2, 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.
