TeMoWSe2S
TeMoWSe2S is a metastable, semimetallic multinary chalcogenide composed of molybdenum, tungsten, sulfur, selenium, and tellurium.
About TeMoWSe2S
TeMoWSe2S is a complex multinary chalcogenide incorporating molybdenum, tungsten, sulfur, selenium, and tellurium. As a near-zero-gap semimetallic material, it exhibits electronic behavior that bridges the gap between traditional semiconductors and metallic conductors, making it a subject of interest for fundamental studies in condensed matter physics.
This material is characterized by its metastable nature, which suggests a delicate structural arrangement that is highly sensitive to synthesis conditions. Given its composition of transition metals and multiple chalcogen species, it represents a synthetic challenge that offers potential for tuning electronic properties through atomic-scale engineering.
Key Properties
Cross-validated computational properties for TeMoWSe2S, 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.
