In2PO5
In2PO5 is a thermodynamically stable, semiconducting transparent conducting oxide used in the development of advanced electronic and optical materials.
About In2PO5
In2PO5 is a semiconducting oxide that sits firmly on the convex hull, indicating significant thermodynamic stability. As a member of the transparent conducting oxide family, it possesses a structural and electronic profile that makes it a compelling candidate for advanced electronic and optoelectronic device architectures.
Its role within the broader class of conducting oxides is defined by its specific indium-phosphorus-oxygen framework. This composition allows for a unique balance of transparency and charge carrier mobility, positioning it as a specialized material for next-generation thin-film technologies where stability and electronic performance are paramount.
Key Properties
Cross-validated computational properties for In2PO5, 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.
