Outline of Final Research Achievements

In order to investigate the interaction between light and materials at the atomic level, this study aimed at achieving a scanning probe microscope that could measure interaction force due to light incident onto a surface, and at investigating atom manipulation process to fabricating nano-clusters at room temperature. We have succeeded in realize atomically flat surface of transparent samples of Al2O3 and LaAlO3, SrTiO3. These would be shaped to prisms as substrate for light incident experiments in atomic level. We have developed a prism sample holder capable of heating that is needed for realizing the atomically flat surface. On the Al2O3 (0001) surface, we have succeeded in resolve atom in the unit cell. In the atom manipulation experiments, we performed nano-fabricating in which nano-clusters were made in the half unit cell of the Si (111) at room temperature environment. Au, Sn and Pb were used for creating clusters.
