Outline

Nano-structured Complex Electron Systems Research Team

Our team aims to understand fundamental microscopic properties of complex electronic materials and to develop the architecture of concerted and innovative energy technology, using new phenomena based on a variety of electronic phases of complex electronic systems. We observe local electronic states, phase transitions at surfaces and interfaces of complex electronic materials with local probe microscopy and spectroscopy. In addition we propose basic principles for the practical application of materials and high efficiency energy conversions using external stimuli-sensitive materials near the phase transition.

Recent Research Topic

The concerted and innovative collaboration between complex electronic materials and nanoscience
