Abstract

Thermoelectric materials have gathered immense research interest in the last few decades due to their worth in interconverting heat as well as electricity. Thermoelectric materials are characterized by figure of merit (zT) and they show large Seebeck coefficient, high electrical conductivity, and low thermal conductivity. These requirements are tough to handle together as all of these parameters depend on carrier concentration, which cannot be tuned independently. The current chapter summarizes and explains the latest efforts of various researchers in improving the thermoelectric performance of distinct thermoelectric materials. These thermoelectric properties can be easily tailored by tacking dopants, introducing defects, forming nanostructures, and creating quantum dots.
