| Abstract: | (Bi,Sb)_2Te_3 及びZnSb のナノ粒子を化学合成し、それらを構成要素とした超格子構造を作製することでナノ粒界を有した高ZT 熱電材料を創製することを試み、以下の成果を得た。(1) (Bi,Sb)_2Te_3 ナノワイヤ合成法を確立。(2) (Bi,Sb)_2Te_3 ナノワイヤ高次構造を塗布プロセスによって固体基板上に作製し、その熱電特性を明らかにした。(3) ZnSb ナノ粒子の合成法を確立し、その熱電特性を明らかにした。 : We successfully synthesized thermoelectric (TE) Bi-Sb-Te and Zn-Sb nanoparticles (NPs). Then, higher-order structures (superlattice structures) composed of those TE NPs as building blocks could be fabricated. In consequence, we obtained the following results: (1) A synthesis method for single-phase (Bi,Sb)_2Te_3 nanowires (NWs) was developed; (2) Higher-order structures composed of (Bi,Sb)_2Te_3 NWs were created using wet-chemical processes and their TE properties were measured; (3) a synthesis method for ZnSb NPs was developed and their TE properties were measured. |
