Molybdenum trisulfide is a semiconducting transition-metal compound characterized by its metastable nature and diverse structural possibilities.
About molybdenum trisulfide
Molybdenum trisulfide is a semiconducting transition-metal dichalcogenide that occupies a distinct position in inorganic chemistry. While it shares elemental components with more common sulfides, its unique stoichiometry and structural configuration make it a subject of significant interest for researchers investigating non-stoichiometric metal-sulfur systems.
Due to its position above the thermodynamic hull, this compound is considered metastable, which drives extensive investigation into its synthesis and phase transformation pathways. Its structural complexity is highlighted by the large number of reported configurations, reflecting its versatility in experimental material science.
Key Properties
Cross-validated computational properties for molybdenum trisulfide, 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.

How It Compares
Within the transition-metal dichalcogenides class.
Unlike the highly stable and widely utilized MoS2, which serves as a benchmark for two-dimensional semiconductors, molybdenum trisulfide exhibits different thermodynamic characteristics and structural diversity. While MoS2 and MoSe2 are prized for their robust layered architectures, MoS3 provides a different chemical profile that is often explored for its potential in catalytic applications and energy storage frameworks where non-stoichiometry can be leveraged.
