Large reduction of thermal conductivity leading to enhanced thermoelectric performance in p-type Mg3Bi2–YbMg2Bi2 solid solutions

Intensifying the phonon scattering via point defect engineering has been demonstrated to be particularly effective in minimizing the lattice thermal conductivity for enhancing thermoelectric performance. In this work, significant phonon scattering has been realized by alloying YbMg2Bi2 with Mg3Bi2....
