Meeting 2018 TMS Annual Meeting & Exhibition
Symposium Alloys and Compounds for Thermoelectric and Solar Cell Applications VI
Presentation Title Thermoelectric Borides and Sulfides; Role of Magnetism and Disorder
Author(s) Takao Mori
On-Site Speaker (Planned) Takao Mori
Abstract Scope High-temperature thermoelectric (TE) applications may be implemented quickly [1]. Borides are promising for this, with recent developments like huge ZT enhancement in Sm- and Yb-borides, and p, n control. Magnetic compounds are gaining attention as TE properties were demonstratively enhanced through magnetism [2]. Thiospinels were considered low performance TE materials, but by some unusual doping of Cr with Sb, we obtained ZT≈0.43 for CuCr2-xSbxS4 [3]. Temperature dependence is unusual with Seebeck coefficient and electrical conductivity both rising with temperature, reminiscent of disordered variable-range-hopping compounds but with much better TE. I will discuss the role of magnetism and disorder in TE properties. [1] JOM, 68, 2673 (2016). [2] Angew. Chem. Int. Ed., 54, 12909 (2015), J. Mater. Chem. A, 5, 7545 (2017). [3] Chem.
