Outline

The goal of this research is to realize all-oxide thermoelectric conversion devices by means of spin current. I utilize 5d electron systems including iridium oxides, which are characterized by cooperation between Coulomb interaction and spin-orbit interaction; high conversion efficiency is expected by fine-tuning these interactions. Performance of the spin-current-driven thermoelectric conversion is proportional to the device area and therefore large-area devices consisting of 5d oxide thin films show promise for the application in stand-alone power sources of wireless sensor nodes in the Internet of Things.
