| Outline of Final Research Achievements |
Synthetic process to obtain large-area films or fois of TiS2/organic hybrid superlattice materials through mechanical intercalation, liquid-exfoliation, and self-assembly of nanosheets.The resulting films or foils are extremely flexible and were found to exhibit higher thermoelectric performance than pristine TiS2 single crystals. A prototype of thin-film thermoelectric device was constructed by combining our newly developed n-type material with p-type organic material, PEDOT:PSS, and it's power generation characteristics was found to be improved compared to a p-type unileg device. In contrast, drastic improvement in thermoelectric performance of SrTiO3 (STO) materials was not achieved, though we succeeded in constructing 3D superlattice ceramics by self-assembling STO nanocubes with Nb-doped surfaces.
