YSnO2
YSnO2 is a metastable semiconducting oxide investigated for its potential role in transparent conducting material applications.
About YSnO2
YSnO2 is a complex oxide belonging to the family of transparent conducting oxides. As a semiconducting material, it represents an interesting subject for researchers investigating the electronic behavior of yttrium-tin-oxygen systems in thin-film applications. Its existence across multiple structural databases highlights the ongoing interest in characterizing its potential phases despite its thermodynamic metastability.
Because it sits above the hull, YSnO2 is considered a metastable compound, which poses unique challenges for synthesis and practical integration. Understanding its structural variations is essential for determining whether specific processing conditions can stabilize this material for use in electronic or optoelectronic devices where transparent conductivity is required.
Key Properties
Cross-validated computational properties for YSnO2, 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.
