MnTe2Zn
MnTe2Zn is a semiconducting ternary compound that is theoretically stable enough to be synthesized for potential electronic or material science applications.
About MnTe2Zn
MnTe2Zn is an intriguing ternary compound composed of manganese, tellurium, and zinc. Its electronic character as a semiconductor makes it a subject of interest for potential optoelectronic or thermoelectric applications where specific band structures are required for device performance.
As a near-hull material, it sits in a favorable energetic position that suggests it is likely synthesizable under appropriate experimental conditions. The existence of multiple reported structures across databases highlights its structural complexity and the potential for polymorphic variations that could be tuned for specific functional properties.
Key Properties
Cross-validated computational properties for MnTe2Zn, 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.
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.
