SmAsSe
SmAsSe is a thermodynamically stable semiconducting compound containing samarium, arsenic, and selenium.
About SmAsSe
SmAsSe is a distinct ternary compound composed of samarium, arsenic, and selenium. As a thermodynamically stable material situated on the convex hull, it represents a robust phase within its chemical system, offering a reliable structural foundation for further investigation.
Characterized as a semiconductor, this material holds interest for researchers exploring the intersection of rare-earth elements and chalcogenide-pnictide chemistry. Its electronic properties suggest potential utility in specialized semiconductor applications where precise control over charge carrier behavior is required.
Key Properties
Cross-validated computational properties for SmAsSe, 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.
