Outline of Final Research Achievements

Nanometer order observation of ice crystal growth in the environment around zero degree with atomic force microscopy (AFM) has been difficult since optical beam detection system used for AFM cantilever detection generate heat in the equipment of AFM. In this study, in order to resolve this problem, a new AFM that does not use the optical beam detection system was developed. We have employed a self-detection type resonator in order to measure the surface at the molecular resolution. We succeeded in imaging NaCl and CaCO3, HOPG (Highly Oriented Pyrolytic Graphite) surfaces. On the other hand, it could not be considered a negative frequency shift which is considered necessary for atomic resolution of the frequency modulation mode AFM.
