The Surface Nanostructure Laboratory creates, characterizes, and exploits nanostructures (1 ~ 50 nm) on solid surfaces. Of particular interest is to combine particle self-organization and ion/electron beam lithography methods to create novel nanostructures such as surface  magic clusters (SMC), and investigate their physical/chemical properties. Owing to its enhanced stability and reduced size dispersion, SMC is an emerging class of objects with both intriguing scientific interests and potential technological applications. Techniques used in our laboratory include STM, AFM, LEED, AES, SEM, and focused ion beam. To fully utilize these techniques, the Laboratory has also developed new instruments such as the focused ion/electron beam system and explored its applications in nanostructure-related research.
