Re2Si1V1
Re2Si1V1 is a semiconducting ternary compound of rhenium, silicon, and vanadium that exists as a metastable phase.
About Re2Si1V1
Re2Si1V1 is a complex ternary compound composed of rhenium, silicon, and vanadium. As a semiconducting material, it occupies a unique position in the electronic landscape, offering potential for tunable transport properties in advanced solid-state devices.
Despite its existence in multiple reported structural configurations, the compound is characterized as being above the thermodynamic hull. This suggests that while it can be synthesized under specific conditions, it remains a metastable phase that requires careful processing to maintain its structural integrity.
Key Properties
Cross-validated computational properties for Re2Si1V1, 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.
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.
