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
