To enjoy the benefits of science and technology in the 21st century, we must tackle, as is widely argued, the issues of energy, food and the environment instead of developing our civilized societies in the same way as we have done to date. One of the best ways to do so is, we believe, to invent new materials without sticking only to the well-known principles that have already been applied so far. This can be realized by the researchers or engineers who can find the essence of the problems which they are up against and try to solve in their own ways. The mission of our department is to produce such highly-skilled researchers and engineers, particularly in invention or clarifying the mechanisms of new materials. To meet this demand, our staff consists of experts in electrical and electronic engineering, and specialists in solid state engineering and materials chemistry. We hope we can successfully help our freshmen to become such highly-skilled researchers or engineers in the next generation.
