Outline of Final Research Achievements

Tip-enhanced Raman spectroscopy (TERS) enables us to investigate the molecule or crystal structures with spatial resolution below optical limit. In this research, we aimed to fabricate TERS tip with Ag-filled carbon nanotubes (CNT). The following results were obtained. (1)Ag coating on the apex of atomic force microscopy cantilever was successfully demonstrated.(2) CNT growth over the thus coated tip was found to be difficult. Addition of alumina and Pd enabled to grow metal-filled carbon nanotube tips.(3)Successful TERS measurement was demonstrated using Ag/SiO2 coated cantilevers.
