CrTe
CrTe is a metallic chromium telluride compound known for its structural complexity and its status as a metastable material in solid-state research.
About CrTe
CrTe is a metallic compound composed of chromium and tellurium. Its electronic character is defined by a lack of a band gap, marking it as a conductive material within the transition metal chalcogenide family.
Despite its thermodynamic status as a metastable phase situated above the hull, this compound has garnered significant attention in materials science. It is characterized by its high structural diversity, with numerous reported configurations across various databases.
Key Properties
Cross-validated computational properties for CrTe, 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.
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.
