Cr3Se
Cr3Se is a metallic chromium selenide compound that exists as a metastable phase in the chromium-selenium material system.
About Cr3Se
Cr3Se is a metallic chromium-based selenide that exhibits complex structural behavior. As a compound characterized by its metallic electronic nature, it represents an interesting subject for studying transition metal chalcogenide interactions. Its existence across multiple databases highlights its prominence in computational research despite its metastable state.
Because it resides above the thermodynamic hull, Cr3Se is considered a metastable phase. This status makes it a compelling target for researchers investigating synthesis pathways and the stabilization of non-equilibrium materials in the broader family of chromium selenides.
Key Properties
Cross-validated computational properties for Cr3Se, 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.
