INORGANIC/ORGANIC COMPOSITE THERMOELECTRIC CONVERSION MATERIAL AND MANUFACTURING METHOD OF THE SAME

PROBLEM TO BE SOLVED: To provide an n-type inorganic/organic composite thermoelectric conversion material comprising an inorganic material and an organic material and having excellent thermoelectric conversion characteristics in a middle-low temperature region.SOLUTION: In an inorganic/organic composite thermoelectric conversion material, an organic cation and a polar solvent molecule having a relative dielectric constant of 10 or more are introduced between layers of an inorganic material that has n-type thermoelectric conversion characteristics and a layered crystal structure. The interlayer distance of the inorganic material is preferably larger than the interlayer distance in the inorganic material alone and 15Å or less.SELECTED DRAWING: Figure 1 【課題】無機材料と有機材料とからなり、中低温域で優れた熱電変換特性を有するｎ型の無機有機複合熱電変換材料を提供する。【解決手段】無機有機複合熱電変換材料は、ｎ型熱電変換特性を有し層状の結晶構造を有する無機材料の層間に、有機カチオンと、比誘電率が１０以上の極性溶媒分子と、が導入されている。無機材料の層間距離は、無機材料単独での層間距離よりも大きく、１５Å以下であることが好ましい。【選択図】図１
