Herein, we show that we can synergistically optimize the electrical and thermal transport properties of CaMnO3 via doping Sr. All the samples exhibit a single phase with an orthorhombic symmetry within the experimental doping range (0-10%). Sr doping

We propose an effective and rapid route for synthesizing polycrystalline mayenite electride (C12A7:e−) in dense bulk. C12A7:e− bulks with high-density electron doping were obtained via a comprehensive method, which combined Ti powder treatment wi

Mg3Sb2-based thermoelectric materials have poor electrical conductivity which is the key to limit thermoelectric performance that need to be solved. Herein we tuned the carrier concentration of Mg3Sb2-based materials via Ag doping at the Mg sites (at

The enhancement of thermoelectric performance should be a compromise of electrical as well as thermal transports with reasonably little reduction of thermopower. In this study, the effects of co-doping by rare earth Pr and alkaline earth Sr on perovs

The rare earth Pr doped Ca1−xPrxMnO3 (x=0, 0.06, 0.08, 0.1, 0.12, and 0.14) compound bulk samples were prepared to study the effect of Pr doping on thermoelectric transport properties of CaMnO3 compound system. The doped samples exhibited single ph
