Alloy cluster is expected to have unique properties compared to bulk crystal and nanoparticles, but experimental method for alloy cluster is now limited. In this study, direct observation of alloy cluster was conducted by using scanning transmission electron microscopy (STEM) which has atomic resolution. Finally, we succeeded to establish an analytical method for auto-identification of different period metal elements. The present results suggest that direct observation method by STEM is useful for new experimental method for alloy cluster.
