Tl3VS4
Tl3VS4 is a stable semiconducting ternary sulfide compound used in materials science research.
About Tl3VS4
Tl3VS4 is a ternary chalcogenide that exhibits semiconducting behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement of thallium, vanadium, and sulfur atoms. Its structural integrity makes it a subject of interest for fundamental solid-state studies.
The compound is characterized by its well-defined structural framework and electronic properties. Its stability suggests potential for integration into specialized electronic or optical systems where reliable material performance is required.
Key Properties
Cross-validated computational properties for Tl3VS4, 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.
