All materials, when smaller than one nanometer in size, begin to exhibit different properties from those under normal conditions as exemplified by iron and gold: iron becomes nonmagnetic, while gold becomes highly reactive. These materials are the new microscopic materials essential for resource-saving, energy-saving, element strategy, and nanotechnology. They can be manufactured and measured on the surface of a solid at the atomic and electronic level. The Surface and Materials Science Laboratory is studying atomic and electronic structures of surface nanomaterials using unique approaches such as a two-dimensional photoelectron spectrometer, aiming to clarify the physical properties of nanomaterials and to create new functions from the atomic and electronic viewpoint. Our research targets include superstructures on semiconductor surfaces, magnetic thin-films, as well as organic and biological molecule adsorbing surfaces vital to catalysis and molecular electronics.

We provide education not only on experiments but also on what is important as a researcher and a professional engineer, including having an active attitude toward obtaining knowledge through study, originality training, acquisition of technical skills to enhance laboratory techniques (such as shop practice, machine control, and data analysis), and cooperation with laboratory members. We aim for our students to improve or make some apparatuses before graduation. It is important for students not only to learn how to think systematically through seminars or lecturing in turn, but also to have contact with external researchers as well as the regular educational staff in the laboratory. We conduct joint research with several external research institutions including the synchrotron radiation facilities of SPring-8 and the Ritsumeikan University SR Center, and actively dispatch our students overseas.
