SiO4
SiO4 is a semiconducting silicon-oxygen compound that is characterized by its thermodynamic instability and significant structural variety.
About SiO4
SiO4 is a silicon-oxygen compound that exhibits semiconducting electronic behavior. Due to its position above the thermodynamic hull, it is considered an unstable phase that typically requires specific conditions to exist in a laboratory setting.
Despite its instability, the compound is notable for its structural diversity, appearing in a wide variety of reported configurations. It serves as a subject of interest for researchers investigating the complex phase space of silicon-based oxides.
Key Properties
Cross-validated computational properties for SiO4, 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.
