Outline of Final Research Achievements

The simultaneous control of the thermal conductivity and electrical conductivity has been difficult because of their correlation. However, this control is required for the development of the high performance thermoelectric materials. In this study, we developed the coherent nanostructures by stacking of epitaxial nanodots/Si layers, which can exhibit low thermal conductivity and high electrical conductivity. In the developed structures, nanodots played a role of the scattering bodies of phonon wave, leading to the drastic thermal conductivity reduction. On the other hand, by proper doping, the structures showed the bulk-like high electric mobility because nanodot interfaces do not prevent electron transport so much. As a result, we succeeded in the development of the Si-based nanostructures with high electrical conductivity and low thermal conductivity, bringing out the possibility of the realization of high performance Si-based thermoelectric materials.
