Thermoelectric properties of p-type CoSb3 nanocomposites with dispersed CoSb3 nanoparticles
CoSb3 nanocomposites with different contents of CoSb3 nanoparticles were prepared by mixing nanosized CoSb3 particles obtained via polyol method and micron-sized particles obtained via solid state reaction. X-ray diffractometer and field emission scanning electron microscope were used to characte...

description |
CoSb3 nanocomposites with different contents of CoSb3 nanoparticles were prepared by mixing
nanosized CoSb3 particles obtained via polyol method and micron-sized particles obtained via solid
state reaction. X-ray diffractometer and field emission scanning electron microscope were used to
characterize the prepared products. The thermoelectric properties of the nanocomposites with
different amounts of nanoparticles as dispersants were measured from room temperature to around
500 °C. Due to the grain boundaries scattering, the lattice thermal conductivity was observed to
decrease as the amount of nanoparticles increased. The electrical properties were also improved by
the addition of nanoparticles. The ZT value of the nanocomposites with 10 wt % of nanoparticles
was nearly doubled that of the sample without any nanoparticles. |
