Enhanced thermoelectric properties of In-filled Co4Sb12 by dispersion of reduced graphene oxide

“…10 It was found that doping suitable elements at the Co/Sb site and filling the voids within the Co 4 Sb 12 structure with foreign elements can significantly reduce the lattice thermal conductivity through enhanced scattering of phonons. [11][12][13][14][15][16] Also, nanostructuring, dispersion of nano-precipitates or nano-pores in the bulk materials can scatter heat-carrying phonons at the interfaces, reducing the lattice thermal conductivity. [17][18][19][20][21][22][23] A combination of different approaches proved to be more efficient in tuning all the thermoelectric properties simultaneously.…”
