Ga3NO3 is a metastable semiconducting oxynitride material studied for its potential roles in transparent electronic and optoelectronic technologies.
About Ga3NO3
Ga3NO3 is a semiconducting oxynitride that occupies a unique niche within the broader family of transparent conducting oxides. Its complex composition and metastable nature make it a subject of significant interest for researchers aiming to tune electronic properties for next-generation optoelectronic devices.
This material is primarily investigated for its potential to bridge the gap between traditional oxide semiconductors and nitride-based systems. By leveraging its distinct structural characteristics, scientists explore its utility in applications requiring high transparency combined with controlled charge carrier mobility.
Key Properties
Cross-validated computational properties for Ga3NO3, 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 stable and widely utilized ZnO, which serves as a benchmark for transparent conductors, Ga3NO3 represents a more specialized, metastable phase. While materials like BaSnO3 are prized for their robust conductivity, Ga3NO3 offers a different structural framework that allows for distinct electronic behavior, positioning it as a specialized candidate for research compared to the more conventional spinel-structured oxides like ZnGa2O4.
