About rhenium disulfide
Rhenium disulfide is a semiconducting transition-metal dichalcogenide that occupies a stable position on the thermodynamic convex hull. Its distinct structural arrangement, characterized by rhenium-rhenium bonding, differentiates it from more common layered dichalcogenides and provides a unique platform for studying low-dimensional physics.
Due to its robust stability and favorable electronic properties, this material is a subject of intense research for next-generation optoelectronic and sensing devices. Its ability to maintain structural integrity while offering tunable electronic responses makes it a versatile candidate for advanced material engineering.
Key Properties
Cross-validated computational properties for rhenium disulfide, aggregated across 5 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 more widely characterized hexagonal MoS2 or MoSe2, ReS2 exhibits a distorted triclinic structure that leads to significant in-plane anisotropy. This structural deviation from its siblings allows for direction-dependent optical and electronic behaviors, positioning it as a specialized alternative to the highly symmetric members of the transition-metal dichalcogenide family.
