bismuth antimony telluride nano-bulk composites with high figures of merit (zt)

摘要

According to various aspects, exemplary embodiments are disclosed of Bismuth Antimony Telluride (BiSbTe) based nano-bulk composites having high dimensionless figures of merit (ZT) and with nanostructured BiSbTe as the matrix (host) and bulk BiSbTe as the inclusion (guest). In an exemplary embodiment of a thermoelectric nano-bulk composite material, there is a matrix including nanostructured bismuth antimony telluride. The thermoelectric nano-bulk composite material also includes bulk bismuth antimony telluride in the matrix. A weight percentage ratio of the nanostructured bismuth antimony telluride to the bulk bismuth antimony telluride is at least one to one or higher.
