Boosting Thermopower of Oxides via Artificially laminated Metal/Insulator Heterostructure
Ultra-thin metal oxide LaNiO3 sandwiched between two insulating layers of LaAlO3 exhibits a 10-fold increase of voltage caused by thermoelectric energy conversion, scientists from Tokyo Tech have demonstrated. This discovery opens up new avenues for development of high-performance thermoelectric materials by designing the laminate structure of different oxides.
