Effect of microstructure on the thermoelectric performance of La1−xSrxCoO3
(2016)We present a case where the microstructure has a profound effect on the thermoelectric properties of oxide compounds. Specifically, we have investigated the effect of different sintering treatments on La1−xSrxCoO3 samples ...
