High-Performance Mg3Sb2-xBix Thermoelectrics: Progress and Perspective

Figure 6

(a) Temperature-dependent for Mg3Sb2-xBix synthesized with different grain sizes. The data are taken from Refs. [78, 82]. (b) 3D reconstruction of the atom distribution of the microtip of n-type Mg3Sb2. The upper-right inset is a scanning electron microscope image of the APT specimen. (c) The and at RT versus grain size for Mg3(Sb,Bi)2 solid solutions, adapted from Ref. [48] with the data taken from Refs. [33, 47, 48, 78, 79, 166, 178]. (d) at RT for SC and PC samples with different compositions and preparing methods. The data are taken from Refs. [48, 70, 73, 82, 96, 136]. Panel (b) is reproduced with permission from Ref. [98].
