Outline

Functional Superstructure Team

Artificial interfaces and superlattices are designed and constructed with the aid of cutting-edge thin film technology of transition-metal oxides having various ordered structures in charge, spin and orbital degrees of freedom of electrons. The responses of these superstructures to such stimuli as magnetic field, electrical field and photo irradiation are examined to elucidate cross-correlated functionalities. These studies will enable us to create new kinds of devices such as switches, memories, photovoltaics and sensors based on a novel concept of gigantic cross-correlation effects.
