Cu3Te
Cu3Te is a metallic copper-tellurium compound that exists as a metastable phase with multiple reported structural variations.
About Cu3Te
Cu3Te is a metallic binary compound composed of copper and tellurium. As a material that lacks a band gap, it exhibits characteristic metallic electronic behavior, making it an interesting subject for studies into the complex phase space of copper-chalcogenide systems. Its existence is marked by a significant number of reported structures across various databases, highlighting its structural diversity despite its metastable nature. Because it sits above the thermodynamic hull, Cu3Te is generally considered an unstable phase under standard conditions, often requiring specific synthesis pathways to stabilize its configuration. It serves as a valuable case study for researchers investigating the formation and transformation of non-equilibrium phases in metallic alloys.
Key Properties
Cross-validated computational properties for Cu3Te, 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.
