We aim to cultivate researchers who will carry out investigations on new physical phenomena and devices at the mesoscopic scale, and who will promote interdisciplinary research and open up new research areas. In the master’s program, we first provide students with a basic education in order for them to grasp the reasons why our research is necessary for society, and why research in science and technology is essential for the development of humankind. Then, based on this education, students participate in our research activities in mesoscopic and nano fields, experiencing the joy of new discoveries and skilled manufacturing through experiments. Thus, we nurture researchers who can take on basic responsibilities in the development of new science and technology.

In the doctoral program, we not only provide guidance on specific research themes but also clarify the difference between science and engineering, thus providing students with adequate guidance so that they can, in a balanced manner, utilize both a scientific mindset that leads to paradigm shifts, and engineering knowledge that serves to realize scientific ideas.

We conduct research on exotic devices utilizing new physical phenomena in the mesoscopic region that take advantage of thin-film technology. Specifically, we are conducting research on novel energy conversion devices using strongly-correlated electronic materials and/or solid-state iontronics materials.
