研究の背景 Background


The main purpose of this department is to newly construct function harmonized nano-materials and nano-devices based on novel nano-scale physical mechanism. By using typical "Bottom-up Nanotechnology" of artificial lattice technique , we combine exotic materials which exhibit ferroelectric/ferromagnetic/semiconductive properties and so on at atomic/molecular level to new functional nanomaterials. We also develop nano-fabrication technique for the new functional nano-materials by fusion of Bottom-up and Top-down Nanotechnologies, and construct spatially and dimensionally controlled nanodevices toward new functional electronics application.

研究の目標 Outcome


Transition metal oxides exhibit a rich variety of attractive properties such as a metal-insulator transition (MIT), colossal magnetoresistance, and High TC ferromagnetism due to their strongly correlated electrons. We produce novel electronics devices to control their MIT and ferromagnetism in 3D nanostructures and heterostrcutures toward functional oxide nanoelectronics and spintronics.
