Abstract
Toward advanced information the oriented society, the creation of novel functional sensors and devices which can detect many kinds of information such as electric field, magnet field and light will become important to realize flexible information and transfer processes in human bodies. The transition metal oxides possess numerous functional properties, including ferroelectric-piezo-electric, photoactive, ferromagnetic, spin glass, and superconductive properties. By integrating these characteristics in function harmonized artificial lattices at atomic or molecular level, it is possible to create highly sensitive sensor materials for external field (super-five senses) and flexible information processing devices (brain type memory) . In this article, we describe how to create novel functional oxide superlattices and heterostructures as sensitive and multi-functional devices.
