Nb1Re1W2
Nb1Re1W2 is a semimetallic ternary compound composed of niobium, rhenium, and tungsten that exists in a metastable state.
About Nb1Re1W2
Nb1Re1W2 is a complex ternary metallic compound composed of niobium, rhenium, and tungsten. Characterized by a near-zero-gap electronic structure, it functions as a semimetal, placing it in a unique position between traditional metallic conductors and semiconductors.
Due to its position above the thermodynamic stability hull, this material is considered metastable. Its existence across multiple reported structural configurations suggests a complex energy landscape that remains a subject of interest for fundamental materials research.
Key Properties
Cross-validated computational properties for Nb1Re1W2, 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.
