SeN
SeN is a semiconducting selenium-nitrogen compound known for its structural diversity in research despite being thermodynamically unstable.
About SeN
SeN is a binary compound consisting of selenium and nitrogen, characterized by its semiconducting electronic behavior. As a material that sits above the thermodynamic hull, it represents a metastable phase that is of significant interest for fundamental studies in chalcogen-nitrogen chemistry.
Despite its inherent instability, the compound is highly data-rich, appearing in numerous reported structures across scientific databases. Its existence provides valuable insights into the bonding interactions between selenium and nitrogen, contributing to our broader understanding of non-metal inorganic frameworks.
Key Properties
Cross-validated computational properties for SeN, 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.
