The broadening of Thermoelectric applications brings about more challenges not only in searching for high ZT materials but also in developing cost-effective, resource-abundant, and environment-friendly TE materials and technologies. A proven approach to improve figure-of-merit is to “decorate” the crystal voids in cage-structured compounds such as the skutterudites. Recently, a new mechanism to tune TE transport properties by “engineering” the crystal structure has also been realized in cupper ion conducting compounds. In the Cu2-xM (M: VI elements) binary system, the M atoms form a rigid face-centered cubic lattice providing a crystalline pathway for semiconducting electrons, while the copper ions are highly disordered around the M sublattice. As the important low-cost thermoelectric material systems, silicides and half-Heusler compounds have also been receiving more attention because of their constituent abundant elements. Continuing efforts on creating new processes with low cost and good scalability are also necessary for both TE materials and device.
