Abstract
Alkali bismuth chalcogenides are promising for thermoelectric applications as suggested by previous works. The K2Bi8Se13 compounds were grown from melt as polycrystalline ingots or from Bridgman technique as highly oriented polycrystalline ingots. In this work, we apply powder techniques as a post-growth process on the K2Bi8−x Sb x Se13 series and the effect of the sintering process and the Sb concentration on the thermoelectric properties of the series is discussed.
