Li5GaO4
Li5GaO4 is a thermodynamically stable, wide-band-gap insulating oxide containing lithium and gallium.
About Li5GaO4
Li5GaO4 is a thermodynamically stable inorganic compound composed of lithium, gallium, and oxygen. As a member of the oxide family often associated with transparent conducting materials, it exhibits a wide-band-gap electronic character that classifies it as an insulator rather than a conductor. Its stability on the convex hull makes it a significant subject for structural research, with multiple reported configurations documented in materials databases. This compound is primarily utilized in fundamental materials science research to explore the limits of ionic conductivity and structural stability in complex lithium-based oxides.
Key Properties
Cross-validated computational properties for Li5GaO4, 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.

How It Compares
Within the transparent conducting oxides class.
Unlike the highly conductive BaSnO3 or the widely used transparent semiconductor ZnO, Li5GaO4 functions as a wide-gap insulator. While many members of this class, such as ZnGa2O4 or CaIn2O4, are engineered for their optoelectronic properties, Li5GaO4 serves as a stable structural reference point that highlights the diversity of electronic behaviors possible within the broader oxide framework.
