The compound is frequently studied for its topological properties and its ability to be tuned for specific thermoelectric performance, positioning it as a significant material in the development of solid-state cooling and power generation solutions.
Key Properties
Cross-validated computational properties for Bi2Te2Se, 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 broader class of bismuth chalcogenides, Bi2Te2Se serves as a strategic alloy that bridges the properties of its parent compounds, such as Bi2Te3 and Bi2Se3. By incorporating selenium into the bismuth telluride lattice, researchers can fine-tune the electronic and thermal transport properties more effectively than in pure Bi2Te3, allowing for optimized performance in specific temperature regimes compared to other members like Sb2Te3 or the more complex Ge2Sb2Te5.
