selenium trioxide · selenic anhydride
Selenium trioxide is a semiconducting binary oxide of selenium that is recognized for its potential for synthesis and structural complexity.
About selenium trioxide
Selenium trioxide is a binary oxide of selenium that exhibits semiconducting electronic characteristics. Due to its position near the thermodynamic hull, it is considered a synthesizable compound of significant interest in inorganic chemistry research.
Its structural diversity is evidenced by a large number of reported configurations within material databases. This complexity makes it a compelling subject for studies focused on the fundamental bonding and stability of chalcogen-based oxides.
Key Properties
Cross-validated computational properties for selenium trioxide, 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.
