Wide Bandgap Materials for High Temperature Thermoelectric Power Generation
Abstract: A total of 3000 trillion BTU/year of waste heat in the US could be directly converted into electricity using high temperature thermoelectric (TE) technology. However, the impact of TE technology is currently limited by the heavy use of toxic and rare materials with low operating temperatures. In this talk, I will present our recent research on nanostructured nitrides and oxides synthesized using advanced metal organic chemical vapor deposition (MOCVD) methods. The resulting materials shows very promising TE properties due to their decoupled electrical and thermal properties. Multiple approaches for further improvement in materials and device structures will be discussed, along with the fundamental understanding of process-structure-property relationships of each material system.
