Rb3InO3
Rb3InO3 is a thermodynamically stable, semiconducting indium oxide used in materials science research.
About Rb3InO3
Rb3InO3 is a thermodynamically stable oxide that sits firmly on the convex hull, indicating robust structural integrity. As a member of the transparent conducting oxide class, it exhibits semiconducting electronic properties that make it a subject of interest for advanced optoelectronic research.
Its structural complexity is highlighted by a significant number of reported configurations across multiple databases. This diversity in structural data underscores its importance as a model system for understanding indium-based oxide behavior in potential electronic applications.
Key Properties
Cross-validated computational properties for Rb3InO3, 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.
