About Ba2YGaSe5
Ba2YGaSe5 is a complex quaternary selenide characterized by its semiconducting electronic nature. Its composition, involving barium, yttrium, gallium, and selenium, places it within a specialized group of chalcogenide materials that are explored for their unique optoelectronic properties.
As a near-hull compound, it is considered thermodynamically stable enough to be a viable candidate for experimental synthesis. The material serves as a platform for studying structural arrangements in quaternary systems and contributes to the broader understanding of semiconductor behavior in complex selenide frameworks.
Key Properties
Cross-validated computational properties for Ba2YGaSe5, 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.
