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.
