About the group


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 ordered arrays of anodic aluminum oxide (AAO) nanochannels. We use AAO as templates to grow arrays of Ag nanoparticles and nanowires. The former is used to enhance the Raman signals of molecules on their surfaces while the latter is used as a metamaterial

 for example.In particular, we are interested in using the Ag-nanoparticle arrays for surface-enhanced Raman spectroscopy (SERS) of bacteria. Techniques used in our laboratory include STM, AFM, LEED, SEM, FIB, Raman Spectroscopy, FTIR, and TEM.
