A high thermoelectric figure of merit ZT > 1 in Ba heavily doped BiCuSeO oxyselenides

A high ZT value of ∼1.1 at 923 K in BiCuSeO oxyselenides has been achieved by the combination of optimizing electrical transport properties through Ba heavily doping and reducing thermal conductivity through refining grain sizes. High performance along with excellent thermal and chemical stabilities makes BiCuSeO very promising for thermoelectric applications.

High thermoelectric figure of merit in nanostructured p-type PbTe–MTe (M = Ca, Ba)

Endotaxially embedding nanocrystals of the alkaline earth tellurides CaTe or BaTe in PbTe doped with Na2Te heat carrying phonons can be strongly scattered with little effect on the power factor. The highest thermoelectric figure of merit, ZT, value achieved is ∼1.5 at 765 K for 6% CaTe containing sample, while 3% BaTe containing sample shows the ZT of ∼1.3 at 760 K.
