Perovskite oxides have attracted considerable attention in the area of thermoelectrics owing to the advantages of their isotropic crystal structure and straightforward control of their electrical properties. Among the many perovskites, different types of polycrystalline Ca1−x R x MnO3 (R: Pr, Nd, Sm) were prepared by solid-state reaction in this study. Three different rare-earth dopants were substituted at the Ca-ion site at various amounts. Considering phase stability, rare-earth ions with nearly the same ionic radius as Ca2+ were selected. To assess thermoelectric performance, the electrical conductivity, Seebeck coefficient, and power factor were measured, and phase analysis was conducted. The effects of ionic radius variation on single phase formation and the effect of doping amount on carrier concentration are discussed.
