Outline of Final Research Achievements

We have developed a novel method to measure the absolute Seebeck coefficient of thermoelectric materials toward the waste heat recovery. We have proposed a novel AC-DC technique, and developed a cryostat system to conduct a proof-of-principle experiments. As a result, we have suceeded in measuring the absolute Seebeck coefficient of a metallic material and thermoelectric material. These results would be useful to evaluate degradation of thermoelectric materials operating at high temperature, and to　develop a high-efficiency thermoelectric materials.
