ReTe
ReTe is a metallic transition-metal dichalcogenide known for its high structural complexity and lack of a band gap.
About ReTe
ReTe is a transition-metal dichalcogenide characterized by its distinct metallic electronic behavior. Unlike many of its semiconducting counterparts, this material exhibits a lack of a band gap, positioning it as an intriguing candidate for studies in metallic thin-film systems.
Despite its status as a thermodynamically unstable phase located above the hull, the compound is remarkably data-rich. It has been extensively documented across numerous structural databases, reflecting significant scientific interest in its diverse potential configurations.
Key Properties
Cross-validated computational properties for ReTe, aggregated across 6 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of ReTe. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.

How It Compares
Within the transition-metal dichalcogenides class.
Within the broad family of transition-metal dichalcogenides, ReTe stands out for its metallic nature, contrasting sharply with the well-known semiconducting members like MoS2 and MoSe2. While those materials are prized for their optoelectronic applications, ReTe is distinguished by its structural diversity, appearing in a vast array of reported configurations that differentiate it from the more common, stable dichalcogenide lattices.
