Abstract: Intermetallic clathrates are candidate materials for thermoelectric applications above room temperature. Here, we explore whether their intrinsically low lattice thermal conductivities can be further reduced by nanostructuring and whether this can further enhance their thermoelectric performance. As bulk nanostructuring routes we studied melt spinning and ball milling. To optimize the compaction process and/or stabilize the nanostructure we varied the process parameters, used additives, and studied clathrate‐based composites. Initial results on clathate nanowires as simpler model nanostructures are also presented.
