Abstract
Nanocomposites have been long exploited for achieving balanced material properties. Here, we synthesized nominal (MgSnSb)-(MgSb) (x = 0-0.15) nanocomposites, achieving a significant reduction of the lattice thermal conductivity of MgSnSb from 2.03 WmK to 1.38 WmK due to phonon scattering by V point defects, MgSb nanoparticles, and heterogeneous interfaces. Hence, a significantly enhanced thermoelectric figure of merit, ZT, is achieved. At 773 K, the sample of x = 0.075 reaches a ZT of 1.4, corresponding to a 14% enhancement compared to the MgSnSb (x = 0) sample. The strategy of introducing heterogeneous structures has important implications for reducing thermal conductivity for other solid-solution thermoelectric systems.
