Enhancement of the Thermoelectric Performance of p-Type Layered Oxide Ca3Co4O9+δ Through Heavy Doping and Metallic Nanoinclusions

An effective way to improve the thermoelectric performance (ZT) of layered structured oxide materials by carefully choosing heavy ion doping and introducing metallic nanoinclusions is proposed. A p‐type oxide material with remarkable highly improved ZT is successfully fabricated using this approach....

Zusammenfassung:An effective way to improve the thermoelectric performance (ZT) of layered structured oxide materials by carefully choosing heavy ion doping and introducing metallic nanoinclusions is proposed. A p‐type oxide material with remarkable highly improved ZT is successfully fabricated using this approach. Long‐term durability at high temperature testing confirms this material is a very promising p‐type material for high temperature power generation.
