“…The Jet Propulsion Laboratory in the United States has conducted extensive research on skutterudite compounds and developed ternary skutterudite compounds . The chemical formula of the multicomponent skutterudite can be written as A x Co 4– x Sb 12– y B y , where A represents elements such as Fe, Ni, Pb, , and B represents elements such as Sn, Te, Se. , The carrier concentration is optimized by element replacement at the Co or Sb sites, and a point defect scattering phonon is incorporated into the lattice to reduce its thermal conductivity. Atoms of different periods are typically used for binary or multiple substitutions at the Sb position of the skutterudite compound.…”

“…Lowering the lattice thermal conductivity of Co 4 Sb 12 is possible though by substituting Co or Sb using single or multiple elements. These dopants introduce defects into the system due to the difference in atomic radii and atomic masses, which will scatter the phonons. Filling the voids by suitable elements also helps to reduce the lattice thermal conductivity. The rattling of elements in the voids scatters the phonons more effectively than doping. The nanostructuring and interface phonon scattering are also effective measures, employed for decreasing the thermal conductivity.…”
