Tl4S3
Tl4S3 is a semiconducting thallium sulfide compound that is theoretically stable enough to be a target for laboratory synthesis.
About Tl4S3
Tl4S3 is a binary sulfide composed of thallium and sulfur. It exhibits semiconducting electronic properties, making it an interesting subject for fundamental research into chalcogenide materials.
Because it is positioned near the thermodynamic hull, Tl4S3 is considered a viable target for experimental synthesis. Its existence across multiple reported structures suggests a complex structural landscape that warrants further investigation for potential electronic or optoelectronic utility.
Key Properties
Cross-validated computational properties for Tl4S3, 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.
