ZnSe2
ZnSe2 is a thermodynamically stable selenium-rich II-VI semiconductor utilized in advanced materials research.
About ZnSe2
ZnSe2 is a distinct member of the II-VI semiconductor family, characterized by its stable structural configuration on the convex hull. As a semiconducting material, it plays a vital role in understanding the electronic behavior of metal-chalcogenide systems where the stoichiometry deviates from the standard binary form.
Its significance lies in its structural diversity, supported by extensive data across multiple databases. This compound serves as a key subject for researchers investigating the fundamental properties of selenium-rich zinc compounds and their potential utility in specialized electronic and optical applications.
Key Properties
Cross-validated computational properties for ZnSe2, 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.

How It Compares
Within the ii-vi semiconductors class.
While common II-VI semiconductors like ZnS and CdSe typically exist in simple binary structures, ZnSe2 represents a more complex stoichiometry within the class. It stands apart from simpler siblings such as CdS or CdTe by incorporating a higher selenium content, which influences its electronic landscape and distinguishes it from the more traditional chalcogenide phases.
