Ga4Na4O8
Ga4Na4O8 is a thermodynamically stable, wide-gap insulating oxide that belongs to the broader category of transparent conducting oxides.
About Ga4Na4O8
Ga4Na4O8 is a complex oxide identified as a stable member of the transparent conducting oxide family. Its electronic structure is characterized by a wide band gap, classifying it as an insulator rather than a traditional conductor, which makes it a subject of interest for fundamental materials research. The compound sits firmly on the convex hull, indicating high thermodynamic stability under standard conditions. Its structural versatility is evidenced by multiple reported configurations, providing a robust foundation for exploring its potential in specialized optical or electronic applications. Due to its unique elemental composition, it serves as a distinct example of how alkali and post-transition metal oxides can be engineered for specific dielectric or transparent material requirements.
Key Properties
Cross-validated computational properties for Ga4Na4O8, 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 transparent conducting oxides class.
While many members of the transparent conducting oxide class, such as ZnO or BaSnO3, are engineered for high electrical conductivity, Ga4Na4O8 functions primarily as a wide-gap insulator. Unlike the spinel-structured ZnGa2O4, which is frequently studied for its phosphor and optoelectronic capabilities, Ga4Na4O8 offers a different structural framework that highlights the diversity of gallium-based oxides in achieving insulating behavior.
