Co1Mn2Mo1
Co1Mn2Mo1 is a semimetallic ternary intermetallic compound composed of cobalt, manganese, and molybdenum that exhibits metastable thermodynamic characteristics.
About Co1Mn2Mo1
Co1Mn2Mo1 is a complex ternary intermetallic compound composed of cobalt, manganese, and molybdenum. Characterized by a near-zero-gap electronic structure, it behaves as a semimetal, placing it in a unique position between traditional metallic conductors and semiconducting materials.
Despite its structural diversity, with numerous reported configurations across databases, this compound is situated above the thermodynamic hull. This suggests that the phase is likely metastable, requiring specific synthesis conditions to stabilize its atomic arrangement.
Key Properties
Cross-validated computational properties for Co1Mn2Mo1, aggregated across 2 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.
