CoTe2
CoTe2 is a thermodynamically stable, metallic cobalt telluride compound known for its structural versatility and conductive properties.
About CoTe2
CoTe2 is a metallic cobalt telluride that occupies a stable position on the convex hull, indicating significant thermodynamic robustness. Its electronic character is defined by its metallic nature, lacking a band gap and exhibiting conductive behavior characteristic of transition metal chalcogenides. The material is highly regarded for its structural diversity, supported by an extensive body of reported data across multiple databases. This wealth of structural information makes it a focal point for researchers investigating the fundamental properties of cobalt-based binary compounds.
Key Properties
Cross-validated computational properties for CoTe2, aggregated across 4 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.
