Design of Advanced Thermoelectric Materials

In this thesis research we have experimentally explored the thermoelectric performance of GeSe-based materials, which according to previous theoretical studies have promising potential for high performance thermoelectric applications. We have also focused on identifying complex lead chalcogenide systems that allow the content of scarce tellurium to be reduced without sacrificing the performance. In addition, our research provides new insight regarding high temperature ferromagnetic properties of Ce-doped PbSe. The outcome of this research provides a great starting point for modifying the presented materials and obtaining further improvements in their thermoelectric properties.
