CrCuSe2
CrCuSe2 is a metastable, semimetallic ternary chalcogenide containing chromium, copper, and selenium.
About CrCuSe2
CrCuSe2 is a complex ternary chalcogenide composed of chromium, copper, and selenium. As a near-zero-gap material, it exhibits semimetallic electronic character that makes it a subject of significant interest for fundamental research into tunable electronic states.
Despite its metastable nature, the compound has been identified across multiple structural databases, reflecting its role as a notable subject for experimental and computational exploration. Its specific arrangement of transition metals and chalcogens provides a distinct platform for investigating charge transport behaviors.
Key Properties
Cross-validated computational properties for CrCuSe2, 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.
