FUNCTIONAL PROPERTIES

INTRODUCTION OF LABORATORY
Solid surfaces are intriguing objects; novel structures and electronic properties emerge as a result of symmetry breaking of bulk. In addition, a solid surface plays an important role as a “low dimensional reaction field”, on which we can supply atoms/ molecules and manipulate them deliberately. In order to fabricate atomically-controlled surface materials, the dynamical behavior of atoms and molecules on surfaces should be understood. These subjects are closely related to the basics of catalysis, semiconductor fabrication, organic devices, solar cells etc. In addition, the concepts in surface chemistry are very useful to understand elementary reactions in environmental and cosmic chemistry. In order to investigate structures, reactions and electronic properties of atoms and molecules on surfaces, we have utilized surface vibrational spectroscopy, photoelectron spectroscopy and scanning tunneling microscopy. Synchrotron radiation (KEK-PF, SPring8 etc.) is also used to study electronic structure of surface and interface．

MESSAGE
EXPERIMENTAL RESEARCH RESEMBLES MOUNTAINEERING.
In both “projects”, we must make a plan carefully and prepare instruments thoroughly. During the experiment, we have to keep the five sensens very keen; otherwise, we may miss important signs which nature shows. We often face difficulties, and depending on the situation we decide if we step forward, change direction or turn back. When various difficulties are overcome, nature shows impressive outcomes. Let’s enjoy this moment!

STUDENT VOICE : YUICHIRO SHIOZAWA
Prof. Yoshinobu has a warm personality. He enthusiastically guides each student in their research and helps them when they have any other problems. The laboratory has an open and free atmosphere. Students have come from a wide range of fields such as chemistry, physics, and engineering. Yoshinobu’s laboratory has various advanced surface analysis systems, and we are constantly conducting cutting-edge research by making full use of these instruments. Although each student has his or her own research theme, synchrotron radiation experiments are conducted in cooperation with other members in the laboratory.

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.
