Cd3Te
Cd3Te is a metallic, metastable cadmium telluride compound that serves as an intriguing subject for structural studies in materials science.
About Cd3Te
Cd3Te is a metallic compound within the II-VI semiconductor family, characterized by its distinct electronic behavior compared to typical insulating or semiconducting members of the class. It represents a complex structural phase that has been extensively cataloged across multiple materials databases.
Due to its position above the thermodynamic hull, this compound is considered metastable, making it a subject of interest for researchers studying phase stability and non-stoichiometric chalcogenide systems. Its metallic nature distinguishes it from the more traditional optoelectronic materials in its group.
Key Properties
Cross-validated computational properties for Cd3Te, 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 ii-vi semiconductors class.
Unlike the widely utilized semiconducting members of the II-VI class such as CdTe or CdS, which are prized for their specific optical properties, Cd3Te exhibits a metallic electronic character. While its siblings are stable, well-characterized semiconductors, Cd3Te exists as a more exotic, metastable phase that challenges the typical bonding trends seen in the cadmium-tellurium binary system.
