Description:: Thermoelectric devices utilize semiconducting n-type and p-type thermoelectric materials to convert heat into electricity. Despite their promise for deep space power generation or waste heat recovery, most high-performing thermoelectric materials reported in literature are absent in practical applications - partially due to inconsistent synthesis and poor mechanical performance. This work...

Description:: Following the discovery of n-type Mg3Sb2−Mg3Bi2 alloys, attempts have been undertaken to optimize their thermoelectric performance because understanding of the properties of this system had been limited due to its novelty. In this thesis, the thermoelectric performance of n-type Mg3Sb2−Mg3Bi2 alloys was systematically investigated and significantly improved. Thorough experimental characterization...

Description:: Thermoelectric modules that convert heat into electrical energy are attractive for improving global energy management. This thesis reports the synthesis and characterization of two new families of lead and tin chalcogenide alloys and focuses on the impact of the grain boundaries, phase segregation, and atomic vacancies on the electronic and...
