About O3PdSe
O3PdSe is a distinct palladium-based selenium oxide that exhibits semiconducting electronic behavior. As a thermodynamically stable compound residing on the convex hull, it represents a robust phase that maintains structural integrity under standard conditions. Its unique combination of transition metal, chalcogen, and oxygen atoms makes it an intriguing subject for fundamental materials research.
The material is characterized by its structural diversity, with multiple reported configurations across various databases. This structural flexibility suggests potential for fine-tuning its electronic properties for specialized applications in sensing or optoelectronic technologies where stable semiconductor materials are required.
Key Properties
Cross-validated computational properties for O3PdSe, aggregated across 4 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
