SiW3
SiW3 is a metallic silicon-tungsten compound that serves as a complex, albeit metastable, candidate for research into advanced anode materials.
About SiW3
SiW3 is a metallic compound composed of silicon and tungsten. It is categorized within the silicon anode material class, representing a complex structural arrangement that has been extensively documented across multiple crystallographic databases.
Due to its position above the thermodynamic hull, this material is considered metastable. Its metallic nature distinguishes it from traditional semiconductor-based silicon anodes, making it a subject of interest for researchers investigating alternative electrode architectures.
Key Properties
Cross-validated computational properties for SiW3, aggregated across 4 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.

How It Compares
Within the silicon anode materials class.
Unlike the more stable and widely utilized silicon-based materials such as Mg2Si or the elemental silicon itself, SiW3 occupies a unique space as a metallic, potentially unstable phase. While compounds like FeSi or MoSi2 are frequently studied for their specific electronic properties, SiW3 stands out for its high structural diversity despite its thermodynamic instability.
