Nanostructuring and Porosity in Anisotropic Thermoelectric Materials Prepared by Bottom-Up Processing

摘要: Nanostructuring has allowed for enhancement in the thermoelectric properties of materials as compared to that bulk. The presence nano-scale inclusions or grains within a bulk matrix seems be beneficial certain cases. In addition, texturing and porosity nanostructured are also important factors, can directly affect properties. Bottom-up processing allows control particle size yield, well quality nanocrystals, while densification by spark plasma sintering preserves nano-inclusions dense material without significant grain growth. Optimization synthesis parameters is therefore critical obtaining materials. Materials with anisotropic crystal structures have additional challenges due possibility alignment during densification, associated effects on physical material. An understanding these state-of-art offers platform expanding investigation into fundamental structural transport other systems potential applications.
