TeMoWSe3
TeMoWSe3 is a semiconducting quaternary chalcogenide compound containing molybdenum, tungsten, selenium, and tellurium.
About TeMoWSe3
TeMoWSe3 is a complex quaternary chalcogenide composed of molybdenum, tungsten, selenium, and tellurium. As a semiconducting material, it represents a synthetic challenge in the development of multi-element transition metal dichalcogenide derivatives. Its electronic character suggests potential utility in optoelectronic or sensing applications where band structure engineering is critical.
Due to its position above the thermodynamic hull, this compound is considered metastable, requiring precise synthesis conditions to stabilize its structure. The existence of multiple reported structural configurations indicates a rich landscape for phase exploration, making it a subject of interest for computational materials design and high-throughput synthesis studies.
Key Properties
Cross-validated computational properties for TeMoWSe3, 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.
