PrAs2
PrAs2 is a semimetallic praseodymium arsenide compound that is theoretically stable and of interest for its electronic properties.
About PrAs2
PrAs2 is a binary intermetallic compound composed of praseodymium and arsenic. It exhibits a semimetallic electronic character, placing it in a unique regime where its conduction properties are highly sensitive to structural configuration.
Due to its position near the thermodynamic stability hull, this compound is considered a viable candidate for experimental synthesis. Its existence across multiple structural databases highlights its significance as a subject for ongoing investigation into rare-earth pnictide behavior.
Key Properties
Cross-validated computational properties for PrAs2, 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.
