Project Description
High-performance thermoelectric materials are essential components of automotive waste heat recovery technology. A successful technology development would save several hundred million gallons of gasoline annually. This project will address a key issue in the study of superior thermoelectric materials, the role of nanostructural features in the electronic, lattice, and mechanical properties of nanostructured bulk materials. (PbTe)1-x(AgSbTe2)x, one of the best intermediate-temperature thermoelectric materials, will be used as a model material system for this study. Lattice dynamics and stress-strain calculations will produce a phonon density of states and atomistic bond-breaking process of the materials, respectively, providing important insights into the mechanisms of the phonon scattering process, structural deformation, and failure modes.
