About tin selenide
Tin selenide is a binary chalcogenide that exists as a thermodynamically stable phase. Its semiconducting nature and unique crystal structure have made it a subject of intense research for its ability to convert waste heat into electricity with high efficiency. The material is highly regarded for its low thermal conductivity, which is a critical trait for high-performance thermoelectric applications. Researchers continue to explore its structural versatility, as evidenced by the numerous reported configurations found in materials databases. This extensive data richness underscores its importance in the development of advanced electronic and optoelectronic devices.
Key Properties
Cross-validated computational properties for tin selenide, 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.
