CsSbSe2
CsSbSe2 is a thermodynamically stable semiconducting ternary chalcogenide used in materials science research for its potential thermoelectric properties.
About CsSbSe2
CsSbSe2 is a semiconducting ternary chalcogenide that exists as a thermodynamically stable phase on the convex hull. Its structural versatility is highlighted by multiple reported configurations across materials databases, marking it as a significant subject for solid-state research.
As part of the broader family of chalcogenide thermoelectrics, this compound leverages the heavy-element chemistry of antimony and selenium to influence its electronic transport properties. It serves as an important model for understanding how alkali metal incorporation modifies the lattice dynamics and electronic structure of traditional chalcogenide semiconductors.
Key Properties
Cross-validated computational properties for CsSbSe2, 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.

How It Compares
Within the bismuth chalcogenide thermoelectrics class.
Within the class of chalcogenide thermoelectrics, CsSbSe2 shares structural and electronic parallels with KSbSe2, yet it occupies a distinct position compared to more conventional binary systems like Sb2Se3 or the widely utilized Bi2Te3. While many of its siblings are binary compounds, the inclusion of cesium allows for unique structural tuning that differentiates its behavior from the standard bismuth-based thermoelectric materials.
