| Research Abstract |
We have studied the friction applied to the molecules on surfaces, which is related with adsorption processes and diffusion processes of molecules so that is very important in the view point of basic sciences. We have tried to observe the mechanisms of molecular friction by using supersonic molecular beam apparatus, spectroscopic method and scanning tunneling microscopy techniques. We have observed migration of NO molecule adsorbed on stepped surface of platinum single crystal since NO reactions on Pt surfaces are related with many catalytic reactions, then, we could observe many phenomena of NO migration and obtain many properties of the migration. In addition, we have develop the technique of using the scanning tunneling microscopy to detect microscopically the migration of molecules on surfaces.
