Abstract:
(EN) In order to provide a thermoelectric conversion material in which the resistivity and the thermal conductivity can both be reduced, a thermoelectric conversion element having a high thermoelectric conversion efficiency in which the thermoelectric conversion material is used, and a thermoelectric conversion module, the thermoelectric conversion material includes a carrier supply phase 20 including an ionized impurity 30 and a parent phase 10 having a lower ionized impurity concentration than that of the carrier supply phase 20, the grain diameter of the parent phase 10 and the carrier supply phase 20 being 100 nm or smaller, and the carriers 40 generated in the carrier supply phase 20 being injected into the parent phase and being transmitted through the mother phase as carriers 41.
(FR) Afin de réaliser un matériau de conversion thermoélectrique dans lequel la résistivité et la conductivité thermique peuvent toutes deux être réduites, un élément de conversion thermoélectrique au rendement de conversion thermoélectrique élevé dans lequel le matériau de conversion thermoélectrique est utilisé, et un module de conversion thermoélectrique, le matériau de conversion thermoélectrique selon l’invention inclut une phase d’injection (20) de porteurs de charge incluant une impureté ionisée (30) et une phase parent (10) dont la concentration en impureté ionisée est inférieure à celle de la phase d’injection (20) de porteurs de charge, le diamètre de grain de la phase parent (10) et de la phase d’injection (20) de porteurs de charge étant inférieur ou égal à 100 nm, et les porteurs de charge (40) générés dans la phase d’injection (20) de porteurs de charge étant injectés dans la phase parent et étant transmis à travers la phase mère en tant que porteurs de charge (41).
(JA) 比抵抗低減と熱伝導率低減とが両立可能な熱電変換材料およびそれを用いた熱電変換効率の高い熱電変換素子並びに熱電変換モジュールを提供するために、イオン化不純物30を含むキャリア供給相20と、キャリア供給相20よりもイオン化不純物濃度が低い母相10とを含み、母相10とキャリア供給相20の粒径が100nm以下で、キャリア供給相20で生じるキャリア40は母相内へ注入されキャリア41として母相内を伝導する熱電変換材料とする。
