Outline of Final Research Achievements

In order to determined the crystal structure of a single particle of the nano-crystal, it is required to measure many diffraction patterns as a function of the rotation angle of the crystal. A four-axes high-precision goniometer, which can adjust the position of the nano-crystal with high accuracy (< 100nm), has been developed in this research. The goniometer enables the strucrtural analysis of the single particle of the nano-crystal.
