YAsO
YAsO is a semiconducting ternary compound of yttrium, arsenic, and oxygen that exists as a metastable phase.
About YAsO
YAsO is a complex ternary compound composed of yttrium, arsenic, and oxygen. As a semiconducting material, it represents a specialized area of inorganic research, particularly in the study of pnictide-oxide systems where structural diversity is common across multiple reported configurations.
Because it exists above the thermodynamic hull, YAsO is considered a metastable phase. Its synthesis and characterization are significant for understanding the stability limits of yttrium-based oxypnictides and the potential for tuning electronic properties in non-equilibrium material systems.
Key Properties
Cross-validated computational properties for YAsO, 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.
