| Outline of Final Research Achievements |
The objective of this study is to evaluate thermoelectric properties of the joined thermoelectric materials in the joined surface direction to verify a possibility of separation of the heat flow and carrier flow in the thermoelectric material. As experimental results, the separation was not directly observed at the measurement of both temperature and potential distributions in the joined materials. It was, however, suggested that there is a high possibility of separation of the heat flow and carrier flow in the thermoelectric material, from the results that 1) it was impossible to apply the simple rule of mixture to the joined thermoelectric materials with a parallel connection, and 2) the thermoelectric properties of the joined thermoelectric materials showed a size effect.
