1. Introduction

Over the past few decades, there has been a revived interest in the field of thermoelectricity. New and advanced thermoelectric (TE) materials have been investigated as an alternate mode of energy conversion for refrigeration and power generation applications (1,2,3). Power generation systems with radioactive thermoelectric generators (RTGs) used by NASA in the deep space missions of the Voyager I and II and the Cassini Mission to Saturn have proved to be highly reliable and long lasting. TE materials and devices are of interest for their reliability and durability, and the technology is also environment friendly and ecologically safe. The ...
