SmS2
SmS2 is a stable, semiconducting compound formed from samarium and sulfur that is frequently studied for its structural properties.
About SmS2
SmS2 is a semiconducting compound composed of samarium and sulfur. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within the samarium-sulfur chemical space, offering consistent structural integrity for experimental and theoretical investigation. Its electronic character suggests potential utility in specialized semiconductor applications where rare-earth metal sulfides are required. The material is characterized by a significant degree of structural diversity, as evidenced by its presence in multiple crystallographic databases, highlighting its importance as a subject of ongoing condensed matter research. Its stability makes it a reliable candidate for studies involving electronic transport and magnetic phenomena.
Key Properties
Cross-validated computational properties for SmS2, 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.
