Te3WO12
Te3WO12 is a metastable semiconducting oxide containing tellurium, tungsten, and oxygen.
About Te3WO12
Te3WO12 is a complex oxide composed of tellurium, tungsten, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple binary oxides, making it a subject of interest for fundamental solid-state studies.
Because this compound is characterized as metastable, it represents a unique phase that requires specific synthesis conditions to stabilize. Its existence across multiple reported structures highlights its structural versatility and the ongoing scientific effort to map its potential in materials science.
Key Properties
Cross-validated computational properties for Te3WO12, 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.
