Development of Tin Compounds with Nano-Micro Hierarchical Structures for Thermoelectrics.

Abstract

Thermoelectric materials convert heat energy into electric energy. Thermoelectric performance of such materials needs to be enhanced in order to achieve higher conversion efficiency. Strategies like introducing point defects in the material, having nano-inclusions can be used to enhance the thermoelectric performance. In this project, we have focused our study on SnS material. We could synthesize SnS using hydrothermal approach by two different methods. SnS synthesized by one method has large particle size of few micrometers, whereas another method gives SnS at nanoscale. We shall use the nano-micro composition strategy to observe any changes in the thermoelectric performance of SnS.
