Outline of Final Research Achievements

We thus have been developed low energy atom scattering spectroscopy (less than 5 keV) for the analysis of insulator surfaces. Low energy atom particle beams were projected onto the sample surfaces to avoid charging effects. In this research, we have been developed the manipulator for insulator samples. The developed one can be rotated for 360 degree in the azimuth angles. Thus, data can be collected for any particular angle to see "atomic structure" of insulator surfaces. So far it takes about 30 min. or more to see the image of insulator surfaces.
