Synthesis, Structure, and High Temperature Thermoelectric Properties of Yb₁₁Sb_9.3Ge_0.5

Abstract

Zintl phase compounds with large unit cells and complex anionic structures such as Yb 11 Sb 10 hold potential for being good thermoelectric materials. Single crystals of Ge-doped Yb 11 Sb 10

Synthesis, structure, magnetism, and high temperature thermoelectric properties of Ge doped Yb14MnSb11

“…Similar to our results for doping Ge into Yb 11 Sb 10 , 31 Yb 14 MnSb 11 only incorporates a small amount of Ge into the unit cell when prepared from a Sn flux. 31 However, unlike in the Yb 11 Sb 10 case, the Ge would not satisfactorily refine on the Sb site. Yb 14 MnSb 11 crystallizes in the Ca 14 AlSb 11 structure type ( Fig.…”

Experimental and theoretical investigations for site preference and anisotropic size change of RE11Ge4In6−xMx (RE=La, Ce; M=Li, Ge; x=1, 1.96)

“…In particular, the series of ternary indide compounds including the RE 11 Ge 8 In 2 (RE = Gd-Tm) system [19] and the RE 11 Tt 4 In 6 (RE = Y, La, Gd-Er; Tt = Si, Ge) system [20,21] has been known for its interesting magnetocaloric effect. Moreover, a series of isotypic binary or ternary pnictides with some triel or tetrel substitutions including the A 11 Pn 10-x T x (A = Rb, Cs, Ca, Sr, Ba, Eu, Yb; Pn = Sb, Bi; and T = Si, Ge, Sn) system [18,[22][23][24] has been thoroughly studied given its particular thermoelectric property. However, despite the large amounts of researches on these systems, the majority of studies have been focused on the crystal structures and the physical properties.…”

Synthesis and thermoelectric properties of BaMn2Sb2 single crystals

“…However, Zintl phase compounds have recently attracted much attention owing to their good thermoelectric properties at high temperatures. Many Zintl phase compounds such as Yb 14 MnSb 11 [13], Yb 11 GaSb 9 [14], Ca x Yb 1 − x Zn 2 Sb 2 [15], BaZn 2 Sb 2 [16], Yb 11 Sb 9.3 Ge 0.5 [17], * Corresponding author. [18] have been studied.…”
