Research Areas
In this project, one of the active research subjects is highly correlated materials based on the oxide materials and molecular materials. However, in our team, we rather explore new material functionalities by designing structures in nanoscale, or by designing hybrid structures with materials with different properties. Nanomaterials, such as carbon nanotubes and semiconductor nanowires in combination with superconducting metals and ferromagnetic metals are within out interest.
