More Information
Summary:The present disclosure provides a novel thermoelectric conversion material. The thermoelectric conversion material of the present disclosure has a La2O3-type crystal structure, and is n-type. The thermoelectric conversion material has a composition represented by Mg < 3 + m-a-b > A < a > B < b > D < 2-e-f > E < e > F < f >. And D is at least one element selected from the group consisting of Sb and Bi. And E is at least one element selected from the group consisting of P and As. And the value of m is from-0.1 to 0.4 (inclusive). And the value of e is from 0.001 to 0.25 (inclusive). A is at least one element selected from the group consisting of Y, Sc, La, and Ce. F is at least one element selected from the group consisting of Se and Te. And the values of a and f satisfy the condition 0.0001 < = a + f < = 0.06. B is at least one element selected from the group consisting of Mn and Zn. And b is from 0 to 0.25 (inclusive). 本公开提供一种新型热电转换材料。本公开的热电转换材料具有La2O3型晶体结构，并且是n型的。热电转换材料具有由Mg3+m-a-bAaBbD2-e-fEeFf表示的组成。D是选自Sb和
