Soft anharmonic phonons and ultralow thermal conductivity in Mg(3)(Sb, Bi)(2) thermoelectrics
The candidate thermoelectric compounds Mg(3)Sb(2) and Mg(3)Bi(2) show excellent performance near ambient temperature, enabled by an anomalously low lattice thermal conductivity (κ(l)) comparable to those of much heavier PbTe or Bi(2)Te(3). Contrary to common mass-trend expectations, replacing Mg wit...
