CoAsSe
CoAsSe is a stable, semiconducting skutterudite material investigated for its thermoelectric properties.
About CoAsSe
CoAsSe is a semiconducting member of the skutterudite family, a class of materials widely recognized for their potential in thermoelectric energy conversion. Its position on the convex hull indicates that it is a thermodynamically stable compound, making it a robust candidate for further experimental investigation and material design.
As a material with a well-documented structural profile, CoAsSe benefits from significant data availability across multiple research databases. Its electronic nature and structural stability make it an intriguing subject for researchers aiming to tune transport properties for efficient heat-to-electricity conversion technologies.
Key Properties
Cross-validated computational properties for CoAsSe, 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.

How It Compares
Within the skutterudite thermoelectrics class.
Within the diverse skutterudite and pnictide class, CoAsSe occupies a distinct niche compared to siblings like CoP2 or FeP. While many members of this group are characterized by their specific metal-phosphide or metal-arsenide frameworks, CoAsSe utilizes a mixed-anion approach that influences its semiconducting behavior, setting it apart from the more common binary phosphides like NiP2 or FeP.
