High-Thermoelectric Performance of Nanostructured Bismuth Antimony
Abstract. The dimensionless thermoelectric figure of merit (ZT) in bismuth antimony telluride (BiSbTe) bulk alloys has remained around 1 for more than 50 years. We show that a peak ZT of 1.4 at 100°C can be achieved in a p-type nanocrystalline BiSbTe bulk alloy. These nanocrystalline bulk materials were made by hot pressing …

The two elements, bismuth (Bi) and antimony (Sb), are both in Group 15 (pnictogen) of the Periodic Table [5,6]. Bismuth is the heaviest element of this group and is often referred to as a "green" metal due to its benign nature and low toxicity compared to the other group 15 elements such as arsenic and antimony [5].
