Outline Activities
Materials are a treasure trove of functions.
Under the slogan of "drawing out the functions of materials and making them into devices," we aim to create new nanostructured materials for the realization of new functions. We have been improving the characteristics of high-temperature oxide superconductors. To improve the characteristics of high-temperature oxide superconductors, we have introduced an "artificial pinning center" that suppresses the motion of vortices. We conducted structural analysis and elucidation of the growth mechanism of one dimensional artificial pinning centers by using a three-dimensional transmission electron microscope. (2007) In addition, we are collaborating with Kyushu Institute of Technology, Nagoya University, Kyoto University, Central Electric Power Research Institute, Tohoku University, etc. in research on high-temperature superconducting thin films. Recommended for students who like traveling and want to study hard.
The current focus of research is the creation of new solar cells. From the band structure, we create new structures with functions. We are creating a new type of solar cell as a model of band concept and crystal growth that will be necessary when considering future functional devices. I would like to nurture such researchers who want to draw water from the fountain of knowledge and share it with everyone. In particular, we instruct students to avoid bad habits such as forgery, plagiarism, theft, and unauthorized use of research funds.

Educational Activities
Mukaida supports those who grows supreme physical insight from our educational activities. I also keep my students away from faculty members nd students who cheat or lie.
