Abstract: In recent decades, renewable energy has attracted a lot of attention due to an increase in the global energy use and depletion of fossil fuel reserves. Thermoelectric materials are expected to play a vital role as green energy generators to overcome the upcoming energy crisis as they can directly convert waste heat into electricity through the Seebeck effect.

The lead-free tin telluride (SnTe) is considered as a potential candidate to substitute lead telluride (PbTe) for thermoelectric power generation based on their similar crystal and electronic structures. However, the relatively high lattice thermal conductivity and low Seebeck coefficient of pristine SnTe are detrimental forreal-life applications. This dissertation explored different doping/substituting/alloying strategies of SnTe to overcome those shortcomings and improve SnTe thermoelectric performance.
