Structure and transport behavior of In-filled cobalt rhodium antimonide skutterudites
The effect of indium icosahedral void-site filling on the transport properties of cobalt and rhodium antimonide solid solutions is investigated. Co4−xRhxSb12 and indium-filled In0.1Co4−xRhxSb12 solid solutions were synthesized. Partial rhodium substitution produces a distinct clustering-induced latt...

| description | The effect of indium icosahedral void-site filling on the transport properties of cobalt and rhodium antimonide solid solutions is investigated. Co4−xRhxSb12 and indium-filled In0.1Co4−xRhxSb12 solid solutions were synthesized. Partial rhodium substitution produces a distinct clustering-induced lattice strain that is partly relieved upon indium substitution into the skutterudite icosahedral void-sites. Indium lowers the thermal conductivity of all samples near room temperature. A distinct increase in thermal conductivity is observed in all indium-filled rhodium substituted samples at elevated temperatures and is attributed to bipolar thermal conductivity. In addition, the indium-filled samples were subjected to a 6-day heat treatment at 673K. Void-site filled indium was found to be metastable at this temperature, and was found to partially precipitate during the 6-day heat treatment; thereby presenting concerns over the long-term stability of thermoelectric devices based on indium-filled skutterudites.
Strain in the cobalt rhodium skutterudite solid solutions decreases upon indium filling [Display omitted] .
► Unfilled and indium-filled cobalt and rhodium skutterudite solid solutions were synthesized. ► Indium filling stabilizes the cobalt and rhodium skutterudite solid solutions. ► The thermoelectric properties of all compositions are reported. ► The thermal conductivity of rhodium-rich compositions is strongly affected by indium filling. ► Void-site filled indium was found to be metastable. |
