Outline of Final Research Achievements |
Atomic force microscopy (AFM) allows us to observe single atoms and molecules on surfaces by measuring interaction force between tip apex atoms and individual surface atoms. Using AFM, we can also measure energy dissipation as well as interatomic forces. We successfully identify silicon atoms and germanium atoms, which have similar chemical characters. It demonstrates that interatomic interaction can be precisely measured by our laser interferometer.
