Abstract

The Seebeck coefficient is a physical parameter routinely measured to identify a material's potential thermoelectric performance. However, researchers employ a variety of techniques, conditions, and probe arrangements to measure to Seebeck coefficient, resulting in conflicting materials data. To compare and evaluate these methodologies, and to identify optimal Seebeck coefficient measurement protocols, we have developed an improved experimental apparatus to measure the Seebeck coefficient under multiple conditions and probe arrangements (300 K to 1200 K). This manuscript will describe in detail the apparatus design and instrumentation, including a discussion of its capabilities and accuracy as measured through representative diagnostics. In addition, this manuscript will emphasize the techniques required to effectively manage uncertainty in high temperature Seebeck coefficient measurements.
