MgTlY2
MgTlY2 is a semiconducting ternary intermetallic compound that is considered potentially synthesizable due to its favorable thermodynamic stability.
About MgTlY2
MgTlY2 is a complex ternary intermetallic compound characterized by its semiconducting electronic nature. Its position near the thermodynamic hull suggests that it is a viable candidate for experimental synthesis and further characterization in materials research laboratories.
This material is of interest due to its unique combination of magnesium, thallium, and yttrium, which allows for diverse structural arrangements. With multiple reported structures across databases, it serves as a subject of study for understanding phase stability and electronic behavior in ternary systems.
Key Properties
Cross-validated computational properties for MgTlY2, 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.
