Tohoku University Technology: Thermoelectric material and thermoelectric module: T16-130
To provide a thermoelectric material having an improved figure of merit.
Development of thermoelectric materials and modules are promoted to effect ively ut ilize unused thermal energy. Thermoelectric materials with nanoparticles have been developed to improve the figure of merit by lowering the thermal conductivity using phonon scattering. However, it is limited to a material in which nanoparticles can be formed, and the dispersion of nanoparticles requires a search for precise conditions and a complicated process. It is an object of the present invention to provide a thermoelectric material and a thermoelectric module having an improved figure of merit, which do not require a process for producing a raw material of nanoparticles, can reduce thermal conductivity by scattering of phonons, can improve electrical conductivity and Seebeck coefficient by quantum confinement effect, and can be expected to be put into practical use.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
