LiYSi
LiYSi is a thermodynamically stable semiconducting material composed of lithium, yttrium, and silicon.
About LiYSi
LiYSi is a ternary compound that occupies a stable position on the convex hull, indicating significant thermodynamic robustness. As a semiconducting material, it offers a unique electronic profile that distinguishes it from simpler binary systems. Its ability to exist in multiple structural configurations suggests a versatile framework for materials engineering. Researchers are particularly interested in how the interplay between lithium, yttrium, and silicon influences its charge carrier behavior and potential for integration into next-generation electronic devices. The stability of this phase makes it a compelling candidate for further experimental investigation in solid-state chemistry.
Key Properties
Cross-validated computational properties for LiYSi, 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.
