ReTe2
ReTe2 is a semiconducting transition-metal dichalcogenide known for its structural complexity and metastable nature.
About ReTe2
ReTe2 belongs to the transition-metal dichalcogenide family, a class of materials widely recognized for their layered structures and tunable electronic properties. As a semiconducting compound, it offers significant interest for researchers investigating the interplay between crystal symmetry and charge carrier behavior in low-dimensional systems.
Although it is classified as a metastable phase, the material exhibits a high degree of structural complexity, as evidenced by the numerous reported configurations in crystallographic databases. This structural flexibility makes it a compelling subject for studies focused on phase engineering and the development of next-generation electronic components.
Key Properties
Cross-validated computational properties for ReTe2, 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.

How It Compares
Within the transition-metal dichalcogenides class.
Unlike the more widely characterized and thermodynamically stable members of the dichalcogenide class such as MoS2 or MoSe2, ReTe2 is distinguished by its metastable nature and unique structural polymorphism. It shares more in common with ReS2 and ReSe2 in terms of its transition-metal backbone, yet it occupies a distinct niche due to the specific bonding characteristics introduced by the heavier tellurium atoms.
