Sandia postdoc Harlan Brown-Shaklee (in the Electronic, Optical, and Nanostructured Materials Dept.) and staff members Jon Ihlefeld (also in the Electronic, Optical, and Nanostructured Materials Dept.) and Peter Sharma (in the Materials Physics Dept.) have built a high-temperature Seebeck and electrical conductivity measurement instrument that can operate over broad atmosphere and temperature conditions.
The Seebeck effect is the conversion of temperature differences directly into electricity, named after German physicist Thomas Johann Seebeck.
Their instrument will enable an understanding of the roles of oxygen vacancies and intentional dopants on the thermopower of oxide thermoelectrics properties and aid in processing and packaging oxide thermoelectric materials for high-temperature applications.
