· JVASP-112996· YbFe4Sb12

YbFe4Sb12 is an intermetallic compound belonging to the skutterudite family, a class of materials characterized by a cage-like crystal structure that hosts rare-earth atoms like ytterbium. This is a research-phase material being investigated for its thermoelectric properties, where the phonon-scattering behavior of the rare-earth filler atoms in the cage structure enables efficient conversion between heat and electrical energy. Skutterudites are promising alternatives to conventional thermoelectric materials in high-temperature applications, offering potential advantages in waste heat recovery systems, radioisotope power generators, and concentrated photovoltaic devices where conventional semiconductors fall short.
