Preparation of Bilayer YBa2Cu3O7-x -NayCoO2 Thermoelectric Ceramic by Solid-state Sintering Method

Preparation of Bilayer YBa2Cu3O7-x -NayCoO2 Thermoelectric Ceramic by Solid-state Sintering Method

Segmented thermoelectric materials have recently been of interest for many heat regulation-related applications such as those in automotive and electronics industries. They are found be highly efficient in converting heat-to-electricity and vice versa. This work attempts to investigate the preparati...
