Research Abstract

Since nanostructure of nanogranular films are closely related with their physical properties, the quantitative characterization of the nanostructure is an important issue. In this study, the analysis method using small-angle neutron and X-ray scattering has been utilized. As a result, the size distribution and the dispersion states of the nanoparticles in the nanogranular films were quantitatively evaluated. In addition, the partitioning state of chemical composition between the nanoparticles and the matrix was quantitatively analyzed.
