SnWO4
SnWO4 is a metastable, wide-gap insulating oxide composed of tin, tungsten, and oxygen that is studied for its unique structural and electronic properties.
About SnWO4
SnWO4 is a complex oxide containing tin and tungsten that functions as a wide-gap insulator within the broader family of transparent conducting oxides. Its electronic structure is characterized by a significant gap between the valence and conduction bands, which limits its intrinsic electrical conductivity under standard conditions.
As a metastable phase, this compound represents a unique structural configuration that is of significant interest for researchers studying phase stability and synthesis pathways. Its existence across multiple crystallographic structures highlights the versatility of the tin-tungsten-oxygen system in forming complex oxide frameworks.
Key Properties
Cross-validated computational properties for SnWO4, 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.

How It Compares
Within the transparent conducting oxides class.
Unlike highly conductive and widely utilized transparent conducting oxides such as BaSnO3 or ZnO, SnWO4 occupies a distinct niche characterized by its insulating nature and metastable state. While many of its class members like ZnGa2O4 are explored for their optical transparency and electronic transport, SnWO4 serves as a specialized subject for investigating the limits of stability and electronic tuning in ternary oxide systems.
