◆Research Interests
Development of nana-mechanics toward atom and molecule manipulation and assembly, and study of reactive dynamics of atoms and molecules on surfaces
We develop novel nano-scale mechanics “nano-mechanics” using noncontact atomic force microscopy (nc-AFM), which is one of new nano-probe techniques, and apply it to manipulation and assembly of individual atoms and molecules on surfaces. Nano-mechanics with nc-AFM has great potential for analysis of surface reaction and fabrication of nano-devices on insulators. This leads to a next generation of science and technology for individual atoms and molecules. 備考
Study of surfaces of semiconductors, metals and oxides with an atomic resolution, thin film growth on them, fabrication of nano structures and field emission related phenomena
We observe condensed matter surfaces and thin film growth with an atomic resolution, and analyze surface electronic states by scanning tunneling spectroscopy and the related techniques. Furthermore, we fabricate nano structures utilizing specific surface structures and hetero growth with strain. 備考
Observation and analysis of surface structures and electronic states on a nano scale by developing instrumentation toward new microscopy and spectroscopy
We develop new methods and construct new instruments on the basis of scanning probe techniques, mainly operated in ultrahigh vacuum. 備考
