Comparison

How It Compares

Within the skutterudite thermoelectrics class.

Within the skutterudite and related pnictide classes, CoSb2 occupies a distinct niche compared to more stable or semiconducting counterparts like FeP2 or CoP2. While many members of this group are prized for their potential in thermoelectric energy conversion due to their favorable band structures, CoSb2 is primarily recognized for its metallic behavior and metastable nature, which sets it apart from the more commonly utilized semiconducting pnictides.
