| Abstract | There is an urgent requirement for improved thermoelectric materials to harvest waste heat energy ('thermo') in the form of electricity ('electric') from a variety of sources, including automobile exhausts, furnaces, chemical and nuclear reactors. These materials can also be used in a 'reverse' mode for applications in refrigeration and solid-state cooling, eg air conditioning units. Current materials are based on toxic, volatile and expensive chemical elements such as Te, Bi and Sb. Due to their volatility they cannot be used for at high temperatures and this restricts their application to near ambient room temperature. Based on encouraging preliminary results obtained in our respective laboratories, we propose to investigate the structure-composition-property relationships of two classes of ferroelectric perovskite-type oxide-based materials (tetragonal tungsten bronzes and hexagonal-type perovskites) with the desired aim of understanding and optimizing their thermoelectric properties. We propose to chemically dope and/or chemically reduce several families of these materials and to measure of all relevant transport coefficients, i.e. electrical conductivity, Seebeck coefficient, and thermal conductivity. We will combine this information with structural and modeling data to obtain a comprehensive understanding of their thermoelectric-ferroelectric properties. We will then focus on using well established ceramic processing procedures to manufacture proto-type thermoelectric devices based on the most promising materials discovered during our studies to test their suitability for thermoelectric applications | |
