Outline of Final Research Achievements

In order to improve the controllability of the lattice (phonon) heat conduction in solid states, which is an important thermal functions to transport, storage, and conversion with solid medium, we developed a phonon engineering technique that couples, theoretical/numerical analysis, material synthesis/fabrication, and physical property measurements. Firstly, we developed methods to evaluate the mode-dependent heat conduction. We then identified the controllability of heat conduction on the basis of the correlation between phonon transport and interface atomic structure. Using the techniques and knowledge obtained thereby, high-performance nanostructured silicon thermoelectric materials was developed. In addition, nanocarbon composites with thermally percolated filler network was developed to enhance both thermal and mechanical properties. Furthermore, we developed a basic analysis technique to calculate phonon transport including their wave nature.
