OsC
OsC is a semiconducting transition metal carbide that exists in a metastable state.
About OsC
OsC is a binary compound composed of osmium and carbon. As a semiconducting material, it represents a specialized niche in carbide chemistry, drawing interest from researchers investigating the electronic behavior of transition metal-carbon systems.
Despite its existence in a high volume of reported structures, this compound is characterized by its thermodynamic instability, placing it above the hull. Its study provides valuable insights into the synthesis challenges and structural diversity inherent in transition metal carbides.
Key Properties
Cross-validated computational properties for OsC, aggregated across 3 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.
