About Mo2Se3S
Mo2Se3S is a complex molybdenum-based chalcogenide that exhibits semiconducting electronic properties. Its structural configuration places it in a category of materials that are theoretically accessible and potentially synthesizable due to its proximity to the thermodynamic hull.
As a member of the transition metal chalcogenide family, this compound is significant for researchers exploring tunable electronic states. Its existence across multiple structural databases highlights its role as a candidate for fundamental studies in solid-state chemistry and materials design.
Key Properties
Cross-validated computational properties for Mo2Se3S, 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.
