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.






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!

Professor Yoshinobu is liked in and out of the laboratory because of his gentle nature. He is a devoted teacher for each student. In our experiments I am often excited when I find out something new which nobody has not seen, because our research could be relevant to the future applications. Since the atmosphere of Yoshinobu laboratory is open, we can discuss everything without distinction of junior, senior or rank even if the theme of each member is independent.
