Thermoelectric materials are highly promising for waste heat harvesting. Although thermoelectric materials research has expanded over the years, bismuth telluride-based alloys are still the best for near-room-temperature applications. In this work, a ≈38% enhancement of the average ZT (300-473 K) to 1.21 is achieved by mixing Bi0.4 Sb1.6 Te3 with an emerging thermoelectric material Sb2 Si2 Te6 , which is significantly higher than that of most Biy Sb2-y Te3 -based composites. This enhancement is facilitated by the unique interface region between the Bi0...
