Enhanced thermoelectric properties in N-type Mg 2 Si 0.4−x Sn 0.6 Sb x synthesized by alkaline earth metal reduction

Year: 2019

Type: article

Abstract: Sb doped Mg 2 Si 0.4 Sn 0.6 materials feature with lots of dislocations at grain boundaries and plenty of nanoscale Mg 2 Si–Mg 2 Sn spinodal phases, both of which can scatter heat carrying phonons and suppress the bipolar effects, with a optimal ZT of 1.42.
