Se2W1Zn1
Se2W1Zn1 is a semiconducting ternary compound containing selenium, tungsten, and zinc that is generally considered to be thermodynamically unstable.
About Se2W1Zn1
Se2W1Zn1 is a ternary compound composed of selenium, tungsten, and zinc. As a semiconducting material, it exhibits electronic properties that make it a subject of interest for fundamental research into complex chalcogenide systems.
Despite its existence in multiple structural configurations within research databases, the compound is characterized by its position above the thermodynamic hull. This suggests that it is likely metastable, requiring specific synthesis conditions to be realized.
Key Properties
Cross-validated computational properties for Se2W1Zn1, 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.
