Research Abstract
Nano-heterostructured ZnO ceramics were prepared by multinary doping and dispersion of metallic nanoparticles into the bulk oxide samples. Significantly different nanostructures with also different scattering mechanisms were obtained with different dopants, suggesting an enhancement of multiple scattering mechanisms might be possible by carefully selecting a combination of dopants. Dispersion of metallic nanoparticles such as Au and Ag were also enabled us to enhance the electrical conductivity and to reduce the thermal conductivity simultaneously. Nanoheterostructures are thereby strongly suggested to be promising to further improve the thermoelectric performance of oxide-based thermoelectric materials.
