Enhanced thermoelectric performance of Ca3Co4O9 ceramics through grain orientation and interface modulation

The commercial application of Ca3Co4O9 ceramics at high temperatures is greatly restricted due to poor thermoelectric properties. One of the approaches to enhance the performance of oxide thermoelectric ceramics is to control the microstructure of the ceramics to provide texturing. Herein, a high fi...
