ENERGY CONVERSION QUANTUM CHEMISTRY

INTRODUCTION OF LABORATORY
To improve the performance of today’s electron devices dramatically, it is essential to incorporate new device materials with higher functionality. In the electron device operations, the carrier density change in semiconductors occurs in the near-interface region within several or tens of nanometers of the interface between the semiconductor and the insulating layer. Therefore, in order to fully utilize new device materials, it is essential to control the atomic arrangement and physical properties in this nano-region near the interface, by designing appropriate fabrication processes based on the deep understanding of the properties of those materials. For example, it is contributing to an energy-saving society to signicantly improve the efciency of power devices for electric power conversion, by fully utilizing wide-gap semiconductors instead of Si as the new device material. The materials showing superior dielectric properties such as ferroelectricity in nanometer-thick lms, are expected to be applied to new non-volatile memory technology that will support the next-generation computing.

MESSAGE
DISCOVER AND OBSERVE PHENOMENA BY OURSELF AND LAY THE FOUNDATION FOR NEW RESEARCH FIELDS. LET’S CREATE WORLD-LEADING RESEARCH FROM JAPAN.
Ever since I was a child, my parents never told me to do anything and I decided on my carrier by myself including the selection of the university. In fact, I never once thought of becoming a researcher until I started my research. I chose to be a researcher because I found that I like doing research.
The field of spin caloritronics has developed from a physical phenomenon I discovered when I was an undergraduate student in Keio University. This is a field that offers great opportunities for students to play an active role. Currently, we are working not only on basic research, but also on how to evelop the various principles discovered in spin caloritronics for practical applications. Our laboratory conducts research in cooperation with Spin Caloritronics Group, Research Center for Magnetic and Spintronic Materials, National Institute for Materials Science (NIMS) in Tsukuba. Students in this laboratory can use state-of-the-art facilities not only at Univ. Tokyo but also at NIMS.

The Goal of Applied Physics
The goal of Applied Physics is to develop a stage = “new material” that can manipulate undeveloped degrees of freedom, to explore unknown phenomena created from that stage and to bring out excellent functions, and to bring out its excellent functions. The purpose is to contribute to the development of human society by elucidating the mechanisms and developing application fields for these phenomena and functions.
