YHO2
YHO2 is a thermodynamically stable, insulating compound consisting of yttrium, hydrogen, and oxygen.
About YHO2
YHO2 is a wide-band-gap insulating compound composed of yttrium, hydrogen, and oxygen. As a thermodynamically stable material residing on the convex hull, it represents a robust structural configuration that has been extensively documented across multiple crystallographic databases.
Its insulating electronic character makes it a subject of interest for specialized dielectric and electronic applications. The structural diversity observed in its reported configurations suggests a complex potential for tuning its physical properties to meet specific technological requirements.
Key Properties
Cross-validated computational properties for YHO2, 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.
