About Te4Mo3S2
Te4Mo3S2 is a complex ternary chalcogenide composed of molybdenum, sulfur, and tellurium. As a semiconducting material, it exhibits electronic properties that make it a subject of interest for researchers investigating non-traditional semiconductor architectures and thin-film technologies.
Although it is classified as a metastable compound, its existence across multiple structural configurations suggests a rich landscape for phase engineering. Its ability to adopt various arrangements makes it a versatile candidate for fundamental studies in solid-state chemistry and materials design.
Key Properties
Cross-validated computational properties for Te4Mo3S2, aggregated across 2 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
