Thermoelectric (TE) power generation, a potential clean power technology, has attracted significant attention owing to the recent development of high-performance TE materials. We focused on Mg2Sn and aimed to improve its TE performance by preparing single crystals (SCs) and introducing lattice defects. In this paper, experimental results on crystal structure analysis, microstructures, and TE properties are presented. It is demonstrated that the TE performance of Mg2Sn SCs can be superior to that of Mg2Sn polycrystals via lattice-defect engineering.
