YSeF
YSeF is a semiconducting ternary compound containing yttrium, selenium, and fluorine that is theoretically predicted to be stable enough for laboratory synthesis.
About YSeF
YSeF is a ternary inorganic compound composed of yttrium, selenium, and fluorine. As a semiconducting material, it occupies a unique position in solid-state chemistry, offering a platform for exploring the interplay between rare-earth elements and chalcogen-halide frameworks.
Due to its near-hull thermodynamic stability, this compound is considered a viable target for experimental synthesis. Its structural diversity, evidenced by multiple reported configurations across databases, suggests a complex potential energy landscape that warrants further investigation for specialized electronic applications.
Key Properties
Cross-validated computational properties for YSeF, 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.
