Skutterudite - Wikipedia
Skutterudite is a cobalt arsenide mineral containing variable amounts of nickel and iron substituting for cobalt with the ideal formula CoAs 3. Some references give the arsenic a variable formula subscript of 2–3. High nickel varieties are referred to as …
Skutterudites as sustainable thermoelectric material- A critical review
2024年11月1日 · In this article, we comprehensively reviewed the thermoelectric proper-ties of skutterudites-based materials. We discussed the various synthesis methods like non-chemical and chemical methods for the synthesis of the skutterudites materials …
Skutterudites - an overview | ScienceDirect Topics
The term skutterudite originally refers to a naturally occurring mineral with the chemical formula CoAs 3, which was mined as a source of cobalt and nickel in Skutterud, Norway.

Skutterudites, a most promising group of thermoelectric materials
2017年4月1日 · Skutterudites derive from the aristotype CoSb 3, a diamagnetic (Co 3+, 3 d 6) narrow band gap (∼0.2 eV) semiconductor with high carrier mobility and relatively large effective electron mass reaching a ZT < 0.8.
Skutterudite | mineral | Britannica
skutterudite, one of a series of cobalt and nickel arsenide minerals that occur with other cobalt and nickel minerals in moderate-temperature veins. The members of the series, which all form crystals of isometric symmetry, are skutterudite and smaltite; their compositions approach that of (Co,Fe,Ni)As 2−3.
A large family of filled skutterudites stabilized by electron count
2015年3月6日 · Here we use this concept to discover a large family of filled skutterudites based on the group 9 transition metals Co, Rh, and Ir, the alkali, alkaline-earth, and rare-earth elements, and...
Several research groups, mostly in the U.S., are now working on understanding and optimizing the transport properties of skutterudites. Most of the efforts are focusing on reducing the lattice thermal conductivity by filling the empty octant cages …
Skutterudites: Progress and Challenges | SpringerLink
2019年12月18日 · Since the discovery of skutterudite (an arsenide mineral (Co, Fe, Ni)As3) in 1845 in Norway, valuable research on isotypic Sb-based skutterudites achieved high-quality thermoelectric (TE) p- and n-type leg materials with remarkably high figure-of-merit ZT, forming...
Skutterudites as thermoelectric materials: revisited
The research on skutterudites in the last few years has contributed to a better understanding of the physical processes which play an important role in enhancing their thermoelectric performance and to the discovery of novel filled compounds, with one of the most promising zT values at intermediate temperatures.
