Strategies to enhance the performance of thermoelectric materials: A review

Abstract

Various techniques to enhance the performance of thermoelectric materials have been reviewed in an unified way. The influence of synthesis techniques, post-synthesis treatment, microstructure, nanostructure, doping, and interface on thermoelectric materials' transport properties has been discussed. The research ideas given by researchers are presented in tabular forms so that young researchers and engineers can find the potential research gaps and best practices in this field. Conclusions drawn from this review would give research directions to the new researchers working in thermoelectric materials.
