Abstract
The lattice thermal conductivity of p-type skutterudite Mm0.8Fe2.7Co1.3Sb12 is reduced to ∼0.69 W m−1 K−1 at 623 K via compositing 0.75 wt% polyaniline nanoparticles. The thermoelectric figure of merit reaches ∼1.16 at 723 K, and the efficiency of a virtual device gets to 10.7% at ΔT = 480 K through finite element simulations.
