TaSN
TaSN is a semiconducting ternary compound of tantalum, sulfur, and nitrogen that is currently the subject of structural research.
About TaSN
TaSN is a complex ternary compound composed of tantalum, sulfur, and nitrogen. As a semiconducting material, it represents a specialized area of inorganic chemistry where the interplay of chalcogen and pnictogen elements creates distinct electronic environments.
While the compound is currently identified as being above the thermodynamic hull, its existence across multiple structural databases highlights its significance in exploratory materials science. Researchers investigate such phases to better understand the stability limits and potential bonding configurations of transition metal nitridosulfides.
Key Properties
Cross-validated computational properties for TaSN, 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.
