Origins of ultralow thermal conductivity in novel Mg-based thermoelectrics
Our study of the atomistic origins of the beneficial ultralow thermal conductivity in novel Mg-based thermoelectrics with Zintl structure Mg3Sb2 and Mg3Bi2 was recently published in Science Advances. Congratulations to Jingxuan who led this study! The project used a combination of neutron scattering measurements at Oak Ridge National Lab, inelastic x-ray measurements at Argonne National Lab, and detailed first-principles modeling of thermal transport.
